【Android】我遇到的bug

44、
git 端口拒绝解决方案 ssh: connect to host github.com port 22: Connection refused
解决：https://blog.csdn.net/s740556472/article/details/80318886
从ssh连接方式换成https连接方式，依然是先查看当前远程仓库使用的那种协议连接：

$ git remote -v
origin  [email protected]:unlimitbladeworks/Data-Struts-Learning.git (fetch)
origin  [email protected]:unlimitbladeworks/Data-Struts-Learning.git (push)

移除掉远程仓库的配置

$ git remote rm origin

重新添加新的远程仓库，以https的形式：

git remote add origin https://github.com/unlimitbladeworks/Data-Struts-Learning.git

再次查看:

$ git remote -v
origin  https://github.com/unlimitbladeworks/Data-Struts-Learning.git (fetch)
origin  https://github.com/unlimitbladeworks/Data-Struts-Learning.git (push)

43、
Caused by: java.lang.IllegalStateException: This Activity already has an action bar supplied by the window decor. Do not request Window.FEATURE_SUPPORT_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead.
解决：
参考：https://my.oschina.net/ocean870227/blog/738442
在style配置文件中加上

<item name="windowActionBar">falseitem>
<item name="windowNoTitle">trueitem>

或者，将parent改为

parent="Theme.AppCompat.Light.NoActionBar"

42、
Android dependency ‘androidx.recyclerview:recyclerview’ has different version for the compile (1.0.0-rc01) and runtime (1.1.0) classpath. You should manually set the same version via DependencyResolution

解决：
Android升级成AndroidX，xml中的控件没有改成AndroidX导致的

41、

java.lang.RuntimeException: Unable to get provider android.support.v4.content.FileProvider: java.lang.ClassNotFoundException: Didn't find class "android.support.v4.content.FileProvider" on path: DexPathList[[zip file "/data/app/com.hi.world.mq-ifYt2PX7TqKZzVF7WTF7mQ==/base.apk"],nativeLibraryDirectories=[/data/app/com.hi.world.mq-ifYt2PX7TqKZzVF7WTF7mQ==/lib/arm64, /system/lib64, /product/lib64]]

java.lang.IndexOutOfBoundsException: Inconsistency detected.
这是google官方bug。这是recyclerview内部进行数据重设置的时候布局刷新出现了问题，这个问题我们只能去捕获这个异常，然后留给Google去解决。

39、
Unknown host ‘jcenter.bintray.com’. You may need to adjust the proxy setting

解决办法：

只要在项目项目build.gradle文件中添加maven { url"https://jitpack.io"}即可。最好加在jcenter()前面

buildscript {
    repositories {
        google()
        maven {url"https://jitpack.io"}
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.0'
    }
}
 
allprojects {
    repositories {
        google()
        maven {url"https://jitpack.io"}
        jcenter()
    }
}

Manifest merger failed : Attribute application@theme value=(@style/Theme.Justtest) from AndroidManifest.xml:11:9-46
	is also present at [com.github.Zenera0301:FreehandsComponents:0.4.0] AndroidManifest.xml:18:9-54 value=(@style/Theme.CaseRecordChoose).
	Suggestion: add 'tools:replace="android:theme"' to <application> element at AndroidManifest.xml:5:5-19:19 to override.

解决办法已经在错误的提示里了：
就是添加：
tools:replace=“android:theme”
在Menifest文件中。

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="com.dj.justtest">

这个问题不好找真正的原因，直到我搜索了Type com.dj.caserecordchoose.BuildConfig is defined multiple times
发现了这个回答https://blog.csdn.net/mp624183768/article/details/106252990

问题解决：
检查不同的程序块里面有一样的包名。
修改其中一个即可。注意使用 批量替换 时应当注意不要全部替换了，不然还会是一样 。

36、
Execution failed for task ‘:app:mergeDexDebug’.
解决：添加multiDexEnabled true

        multiDexEnabled true
    }
}

android 安装apk出错-INSTALL_PARSE_FAILED_UNEXPECTED_EXCEPTION
解決：
将包含错误的多于的xml文件删除即可

31、
异常信息：
Caused by: java.lang.IllegalStateException: This Activity already has an action bar supplied by the window decor. Do not request Window.FEATURE_SUPPORT_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead.

问题原因：
当在activity中调用了setSupportActionBar(toolbar);

解决办法：
增加style，并在AndroidMenifest中调用

增加：
<style name="AppTheme.NoActionBar">
    "windowActionBar">false
    "windowNoTitle">true
style>


调用：
<application
	...
    android:theme="@style/AppTheme.NoActionBar"  
     >

30、
错误: cannot generate view binders java.lang.ClassCastException: android.databinding.tool.expr.IdentifierExpr cannot be cast to android.databinding.tool.expr.StaticIdentifierExpr

将
android:text="@{jniAccessField.num}"
修改为：
android:text="@{String.valueOf(jniAccessField.num)}"


<TextView
    android:id="@+id/tv3"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@{String.valueOf(jniAccessField.num)}"
    app:layout_constraintBottom_toTopOf="@+id/guideline3"
    app:layout_constraintEnd_toStartOf="@+id/guideline"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="@+id/guideline2" />

29、
DSL element ‘android.dataBinding.enabled’ is obsolete and has been replaced with ‘android.buildFeatures.dataBinding’.
解决：
从Android Gradle Plugin4.0.0 开始，有一个被称为buildFeatures启用构建功能的模块，所以要使用新的AGP插件启用数据绑定，得改为以下配置：

android {

    buildFeatures {

         dataBinding true

         // for view binding:
         // viewBinding true
    }
}

28、
java.util.ConcurrentModificationException

原因：对Vector、ArrayList在迭代的时候如果同时对其进行修改就会抛出java.util.ConcurrentModificationException异常
解决方法：

    /**
     * 将ArrayList数组转换成字符串
     * @param arrayList_bytes 需要转换的ArrayList数组
     * @return  返回的String类型变量
     */
    public static String Arraylist_bytes_2_String(ArrayList<byte[]> arrayList_bytes){
        StringBuilder sb = new StringBuilder();
        synchronized (arrayList_bytes) { // 为了防止java.util.ConcurrentModificationException错误，在读取的时候修改了列表会报这个错
            for (byte[] b :
                    arrayList_bytes) {
                sb.append("\n").append(new String(b));
            }
        }
        return sb.toString();
    }

27、
More than one file was found with OS independent path ‘lib/arm64-v8a/libavutil.so’.
意思是加载的so库重复了，那么所有报错误的 .so都选择第一个加载即可：

android {

......

packagingOptions {

    pickFirst 'lib/arm64-v8a/libc++_shared.so'

    pickFirst 'lib/x86/libc++_shared.so'

    pickFirst 'lib/armeabi-v7a/libc++_shared.so'

}
}

26、
执行sh批处理文件报错，原因是文件没有可执行权限

$ sudo ./untitled.sh
Password:
sudo: ./untitled.sh: command not found

给脚本增加可执行权限：

chmod +x untitled.sh

用下列命令查看文件权限

ll untitled.sh # Linux
ls -l  untitled.sh  # Mac

=============================================== 以下是正叙

1、PopupWindow出现Unable to add window – token null is not valid; is your activity running?
参考1
PopupWindow出现android.view.WindowManager$BadTokenException: Unable to add window – token null is not valid; is your activity running?的异常是因为PopupWindow需要依附在一个创建好的Activity上，那么出现这个异常就说明此时你的Activity还没有创建好，出现这种情况，很可能是在onCreate()或者是onStart()中调用导致的。

2、Android error: failed linking file resources
（1）检查一下自己的XML文件中是不是有问题，十有八九是xml的问题。
一般xml文件名不会变红，要手动点开最近修改的xml文件检查是否有红色报错。

（2）十有一二是版本问题：如果遇到了下面的内容error: resource android:attr/dialogCornerRadius not found.说明可能是版本问题，
参考1：https://blog.csdn.net/qq_35366269/article/details/89239440
参考2：https://blog.csdn.net/weixin_43465451/article/details/83185112
参考1中的说法是：将当前项目中的build.gradle文件中的targetSdkVersion和compileSdkVersion 的版本改为28：

3、Android Studio提示Failed to resolve: com.android.support.constraint:constraint-layout:1.0.2
参考：https://blog.csdn.net/qq_36317441/article/details/77451570

//    compile 'com.android.support.constraint:constraint-layout:1.0.1'
修改为：
    implementation "com.android.support.constraint:constraint-layout:1.1.3"

4、

解决方法：
修改注释方式：

5、错误: 程序包okhttp3不存在

解决方法：
修改app目录下的build.gradle文件中dependencies里面添加下面一句代码，导入这个库就好了

compile 'com.squareup.okhttp3:okhttp:3.4.1'

6、canvas.save(Canvas.ALL_SAVE_FLAG)参数数量不对
解决方法：

canvas.save(Canvas.ALL_SAVE_FLAG); 
改为：
canvas.save();

7、fragment 中import androidx.fragment.app.Fragment 和import android.app.Fragment无法相互转换
解决方法：

Android studio 中使用androidx.fragment.app.Fragment实现界面切换，可能会遇到这个问题：

由于将Android studio 版本从2.3版本更新到了3.5版本所以在使用android.support.v4.app.Fragment实现布局切换出现了一些问题，比如说无法导入v4包中的Fragment等问题.
下面我给大家分享一下我自己使用androidx.fragment.app.Fragment实现Fragment界面切换的列子
其实问题都处在使用 FragmentTransaction类进行Fragment页面加载的问题
在V4包中，加载每一个Fragment碎片布局使用的方法如下

首先创建一个fragmentManager对象：
private FragmentManager fragmentManager = null; 
this.fragmentManager = getFragmentManager();

然后利用fragmentManager对象创建一个FragmentTransaction对象：
FragmentTransaction transaction = this.fragmentManager.beginTransaction(); 

最后使用FragmentTransaction中的对象进行Fragment页面布局的加载。

在androidx支持的包中：直接创建FragmentTransaction对象即可，然后调用对象中的方法进行Fragment页面布局的加载

FragmentTransaction ft = getSupportFragmentManager().beginTransaction();

8、Location specified by ndk.dir (xxx) did not contain a valid NDK and and couldn’t be used

导致异常的原因有两个：
1：路径的格式不对（其实一开始就想到这个问题了，我是直接用NotePad++打开的导致没有错误提示）
2：要具体到ndk的版本

解决方法：
打开local.properties，删掉里面的ndk路径那一行即可

9、 java.lang.UnsatisfiedLinkError: No implementation found for int com.baidu.mapsdkplatform.comjni.tools.JNITools.initClass(java.lang.Object, int) (tried Java_com_baidu_mapsdkplatform_comjni_tools_JNITools_initClass and Java_com_baidu_mapsdkplatform_comjni_tools_JNITools_initClass__Ljava_lang_Object_2I)

这是百度地图的问题，去官网下载了最新版本的so库和jar包，so库放到jniLibs文件夹中，jar包放到libs文件夹中，运行即可。

解决办法：

androidx.core.view.ViewPager
换成：
androidx.viewpager.widget.ViewPager

控件如下就不报错了：

<androidx.viewpager.widget.ViewPager
	    android:id="@+id/viewPager"
	    android:layout_width="match_parent"
	    android:layout_height="match_parent"
	    android:layout_alignParentTop="true"
	    android:layout_above="@id/viewGroup"
	    android:layout_marginBottom="10dp"
	    >

12、
报错：
java.lang.IllegalArgumentException: Cannot format given Object as a Number
at java.text.DecimalFormat.format(DecimalFormat.java:507)
at java.text.Format.format(Format.java:157)

这句话报的错：mLatitude = new DecimalFormat("#.000000").format(dfArray[Integer.parseInt(strsFromCaller)][0]);

解决：

mLatitude = new DecimalFormat("#.000000").format(dfArray[Integer.parseInt(strsFromCaller)][0]);

给数据加一层保护层，new BigDecimal(),改为：

mLatitude = new DecimalFormat("#.000000").format(new BigDecimal(dfArray[Integer.parseInt(strsFromCaller)][0]));

13、This project uses AndroidX dependencies, but the android.useAndroidX property is not enabled

解决分两步：

• 第一步：查看下图中的gradle.properties文件是否存在。

若存在进入第二步。
若不存在创建一个同名该文件，并在文件中添加一句org.gradle.jvmargs=-Xmx1536m。

• 第二步：打开该文件，查看是否有下述两条语句，不存在时添加一下即可。

android.useAndroidX=true
android.enableJetifier=true

Cause: d29vzk4ow07wi7.cloudfront.net:443 failed to respond

解决方法：
修改build.gradle文件

添加：
mavenCentral()

repositories {
        mavenCentral()
        google()
        jcenter()
    }

allprojects {
    repositories {
        mavenCentral()
        google()
        jcenter()
        flatDir {
            dirs 'libs'
        }
    }
}

15、
Manifest merger failed with multiple errors, see logs

参考：https://www.liangzl.com/get-article-detail-175677.html

原因：minsdkversion定义为17 小于 library 定义的19，

解决：在主module里面改变build.gradle 的 minsdkversion 改为 19就解决了

16、
java.lang.IllegalStateException: Not allowed to start service Intent

参考：https://blog.csdn.net/shift_wwx/article/details/82258858?utm_source=blogxgwz5

原因：顺利启动service，需要满足下面的条件：

• app 为persistent
• 或 service 的uid 在background 的白名单中
• 或 service 的uid 在device id 的白名单中
• 对于 service 的应用SDK 版本小于O（26），而且AppOpsManager 中是allowed 状态
• 对于SDK 大于等于O（26）的service，不满足上面条件只能选择前台服务，通过 startForegroundService 启动

解决：将targetSdkVersion改成25即可。

17、
Android studio ERROR: Failed to resolve: com.android.support.test.espresso:espresso-core:2.2.2

Android studio跑别人的项目，经常会出现这种不匹配的情况。
解决方法：
添加

maven {
	url “https://maven.google.com”
}

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}

18、
Keystore file D:\Android\tztx.jks not found for signing config ‘config’.

解决：去build.gradle中将不用的内容注释掉

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
//            signingConfig signingConfigs.config
        }
//        debug {
//            signingConfig signingConfigs.config
//        }
    }

19、
Error: Program type already present: com.alibaba.android.vlayout.BuildConfig
依赖重复问题
（1）

在app的build.gradle中加上一句话：multiDexEnabled true

defaultConfig {
   multiDexEnabled true
}

（2）
在app的build.gradle中：

dependencies {
    configurations{
        all*.exclude group:'com.google.android'
        all*.exclude group:'com.alibaba.android'
    }
}


configurations{
    all*.exclude group:'com.google.android'
    all*.exclude group:'com.alibaba.android'
}

（3）参考https://blog.csdn.net/Calvin_zhou/article/details/80880501
maven库搜索方法：
网址：https://mvnrepository.com/search?q=
输入：implementation 'com.alibaba.android:vlayout:1.2.36’中的com.alibaba.android:vlayout:1.2.36
点Vlayout，点1.2.36，下方gradle中：

// https://mvnrepository.com/artifact/com.alibaba.android/vlayout
compile group: 'com.alibaba.android', name: 'vlayout', version: '1.2.36'

20、
The given artifact contains a string literal with a package reference ‘android.support.v4.content’ that cannot be safely rewritten. Libraries using reflection such as annotation processors need to be updated manually to add support for androidx.

参考：https://blog.csdn.net/weixin_39069034/article/details/100600155

（1）安装插件：

（2）添加依赖到项目中：
project依赖

buildscript {
  repositories {
    mavenCentral()
    google()
   }
  dependencies {
    classpath 'com.jakewharton:butterknife-gradle-plugin:10.1.0'
  }
}

（3）mouble 依赖
也就是 app 依赖：

头部添加：

apply plugin: 'com.jakewharton.butterknife'

（4）jar 包依赖：

android {
  ...
  // Butterknife requires Java 8.
  compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
  }
}

dependencies {
  implementation 'com.jakewharton:butterknife:10.1.0'
  annotationProcessor 'com.jakewharton:butterknife-compiler:10.1.0'
}

21、
Android Studio——minSdk(API 24) > deviceSdk(API 23)

解决：
在目录中找到app目录下的build.gradle这个文件，将里面的minSdkVersion 改成23，然后会出现蓝色的顶栏提示，点击Sync Now即可。

如果AS找不到手机，确保手机的开发者模式中开启了USB调试。

22、
bash: ./configure: /bin/sh^M: bad interpreter: No such file or directory

configure文件是dos格式，需要转成Unix格式
这时需要使用到vim

vim configure

:set ff=unix

:wq

然后./configure就可以了

23、
在第三方QQ登录的时候，该应用非官方正版应用，请去应用宝下载正版后进行qq登陆。错误码：100044

解决：检查代码里配置的applicationid是否正确。一定要改成约定的那个字符串。丝毫不能有误。

24、
运行git remote add origin [email protected]:bigyellowdindin/qu-hao-qi.git报错说本地库已经关联了origin的远程库
fatal: remote origin already exists.

解决办法：
（0）可以先 git remote -v 查看远程库信息

（1）先输入$ git remote rm origin(删除关联的origin的远程库)

（2）再输入$ git remote add origin [email protected]:(github名)/(git项目名).git 就不会报错了！

25、

$ git push -u origin master

To gitee.com:bigyellowdindin/DF.git
 ! [rejected]        master -> master (fetch first)
error: failed to push some refs to '[email protected]:bigyellowdindin/DF.git'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

解决方法：https://blog.csdn.net/dietime1943/article/details/85682688

（1）先拉下来，会自动合并的（不用操心）
git pull origin master

（2）再上传
git push -u origin master

或者如果只有一个人用这个仓库，可以用：git push -u origin master强行推送
