Bugly实现热修复采用的是微信Tinker技术。对Tinker进行了简化封装。
Bugly热修复官方文档
添加插件依赖
工程根目录下“build.gradle”文件中添加:
buildscript {
repositories {
jcenter()
}
dependencies {
// tinkersupport插件,其中latest.release指代最新版本号,也可以指定明确的版本号,例如1.0.3
classpath "com.tencent.bugly:tinker-support:latest.release"
}
}
gradle配置
在app module的“build.gradle”文件中添加(示例配置):
dependencies {
compile "com.android.support:multidex:1.0.1"
compile 'com.tencent.bugly:crashreport_upgrade:latest.release'
}
在app module的“build.gradle”文件中添加:
// 依赖插件脚本
apply from: 'tinker-support.gradle'
tinker-support.gradle内容如下所示(示例配置):
需要在同级目录下创建tinker-support.gradle这个文件
apply plugin: 'com.tencent.bugly.tinker-support'
def bakPath = file("${buildDir}/bakApk/")
def appName = "app-0111-15-18-41"
/**
* 对于插件各参数的详细解析请参考
*/
tinkerSupport {
// 开启tinker-support插件,默认值true
enable = true
// 指定归档目录,默认值当前module的子目录tinker
autoBackupApkDir = "${bakPath}"
// 是否启用覆盖tinkerPatch配置功能,默认值false
// 开启后tinkerPatch配置不生效,即无需添加tinkerPatch
overrideTinkerPatchConfiguration = true
// 编译补丁包时,必需指定基线版本的apk,默认值为空
// 如果为空,则表示不是进行补丁包的编译
// @{link tinkerPatch.oldApk }
baseApk = "${bakPath}/${appName}/app-release.apk"
// 对应tinker插件applyMapping
baseApkProguardMapping = "${bakPath}/${appName}/app-release-mapping.txt"
// 对应tinker插件applyResourceMapping
baseApkResourceMapping = "${bakPath}/${appName}/app-release-R.txt"
// 唯一标识当前版本
tinkerId = "1.0.1-base"
// 是否开启代理Application,设置之后无须改造Application,默认为false
enableProxyApplication = false
}
enableProxyApplication = false 的情况
public class SampleApplication extends TinkerApplication {
public SampleApplication() {
super(ShareConstants.TINKER_ENABLE_ALL, "com.yiba.test.buglypatch.SampleApplicationLike",
"com.tencent.tinker.loader.TinkerLoader", false);
}
}
public class SampleApplicationLike extends DefaultApplicationLike {
public static final String TAG = "Tinker.SampleApplicationLike";
public SampleApplicationLike(Application application, int tinkerFlags,
boolean tinkerLoadVerifyFlag, long applicationStartElapsedTime,
long applicationStartMillisTime, Intent tinkerResultIntent, Resources[] resources,
ClassLoader[] classLoader, AssetManager[] assetManager) {
super(application, tinkerFlags, tinkerLoadVerifyFlag, applicationStartElapsedTime,
applicationStartMillisTime, tinkerResultIntent, resources, classLoader,
assetManager);
}
@Override
public void onCreate() {
super.onCreate();
// 这里实现SDK初始化,appId替换成你的在Bugly平台申请的appId
Bugly.init(getApplication(), "900029763", true);
}
@TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH)
@Override
public void onBaseContextAttached(Context base) {
super.onBaseContextAttached(base);
// you must install multiDex whatever tinker is installed!
MultiDex.install(base);
// 安装tinker
// TinkerManager.installTinker(this); 替换成下面Bugly提供的方法
Beta.installTinker(this);
}
@TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH)
public void registerActivityLifecycleCallback(Application.ActivityLifecycleCallbacks callbacks) {
getApplication().registerActivityLifecycleCallbacks(callbacks);
}
}

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.READ_LOGS" />

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<activity
android:name="com.tencent.bugly.beta.ui.BetaActivity"
android:theme="@android:style/Theme.Translucent" />
配置FileProvider(Android N之后配置)
见文档
为了避免混淆SDK,在Proguard混淆文件中增加以下配置:
-dontwarn com.tencent.bugly.**
-keep public class com.tencent.bugly.**{*;}
如果你使用了support-v4包,你还需要配置以下混淆规则:
-keep class android.support.**{*;}
基准包就是原先运行有bug的包。
点击Android Studio右上角的Gradle按钮,找到项目的assembleRelease任务,双击执行assembleRelease任务。
任务执行完成后,会在build的目录下生成如下文件:
修复前代码:
public class BugClass {
public String bug() {
String str = "This is a bug";
str = null;
Log.e("zhang", "BugClass --> bug--> str length :" + str.length());
return str;
}
}
修复后代码:
public class BugClass {
public String bug() {
String str = "This is a bug";
// str = null;
Log.e("zhang", "BugClass --> bug--> str length :" + str.length());
return str + " , fixed!!!";
}
}
调用代码:
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn = (Button) findViewById(R.id.btn);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
BugClass bugClass = new BugClass();
String bug = bugClass.bug();
Toast.makeText(MainActivity.this, bug, Toast.LENGTH_SHORT).show();
}
});
}
}
执行生成补丁包的任务操作:
任务执行完之后,会生成3个文件,其中patch_signed_7zip.apk是我们需要的补丁包
具体见bugly的官方文档。
上传了补丁包可能不会立马生效,多试几次就好
