android应用程序的安装和卸载

A、软件安装代码实现，Action为Intent.ACTION_VIEW

//安装程序的apk文件路径 
String fileName = Environment.getExternalStorageDirectory() + apkName; 
//创建URI 
Uri uri = Uri.fromFile(new File(fileName)); 
//创建Intent意图 
Intent intent = new Intent(Intent.ACTION_VIEW); 
//设置Uri和类型 
intent.setDataAndType(Uri, application/vnd.android.package-archive"); 
//执行意图进行安装 
startActivity(intent);

B、软件卸载代码实现,注意这里Action是Intent.ACTION_DELETE

//通过程序的报名创建URI 
Uri packageURI = Uri.parse("package: poet.android.app.id"); 
//创建Intent意图 
Intent intent = new Intent(Intent.ACTION_DELETE); 
//执行卸载程序 
startActivity(intent);

android应用后台安装，静默安装的代码实现方法

首先，你要有linux环境或其他可以mmm交叉编译的环境，因为这个用到的是隐藏api，SDK中没有的，ecilipse里面会提示包不存在，但交叉编译可以，如果你不知道mmm编译，请return。

代码如下：

import android.app.Activity;
import android.os.Bundle;
import android.content.Intent;
import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;
import android.content.pm.PackageManager.NameNotFoundException;
import android.content.pm.IPackageInstallObserver;
import android.content.res.Resources;
import android.graphics.drawable.Drawable;
import android.net.Uri;
import android.os.Environment;
import android.os.Handler;
import android.os.Message;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ProgressBar;
import android.widget.TextView;

public class InstallActivity extends Activity {
    /** Called when the activity is first created. */
    private Button btn2=null;
    private final int INSTALL_COMPLETE = 1;
    final static int SUCCEEDED = 1;
    final static int FAILED = 0;
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        btn=(Button) findViewById(R.id.btn2);

        btn2.setOnClickListener(listener2);

}

 private OnClickListener listener2=new  OnClickListener(){
        public void onClick(View v) {
            String fileName = Environment.getExternalStorageDirectory() +  "/baidu/"+"UC.apk"; 
            Uri uri = Uri.fromFile(new File(fileName));

            int installFlags = 0;
            PackageManager pm = getPackageManager();
            try {
                PackageInfo pi = pm.getPackageInfo("com.uc.browser", 
                        PackageManager.GET_UNINSTALLED_PACKAGES);
                if(pi != null) {
                    installFlags |= PackageManager.INSTALL_REPLACE_EXISTING;
                }
            } catch (NameNotFoundException e) {
            }


//            String installerPackageName = getIntent().getStringExtra(
//                    Intent.EXTRA_INSTALLER_PACKAGE_NAME);
            
            PackageInstallObserver observer = new PackageInstallObserver();
            pm.installPackage(uri, observer, installFlags, "com.uc.browser");
 

        }
    };
    
    class PackageInstallObserver extends IPackageInstallObserver.Stub {
        public void packageInstalled(String packageName, int returnCode) {
            Message msg = mHandler.obtainMessage(INSTALL_COMPLETE);
            msg.arg1 = returnCode;
            mHandler.sendMessage(msg);
        }
    };
    
    private Handler mHandler = new Handler() {
        public void handleMessage(Message msg) {
            switch (msg.what) {
                case INSTALL_COMPLETE:
                    // Update the status text
                    // Show the ok button
                    int centerTextLabel;
                    Drawable centerTextDrawable = null;
                    if(msg.arg1 == SUCCEEDED) {
                        
                    } else {}
                    if (centerTextDrawable != null) {}

                    break;
                default:
                    break;
            }
        }
    };
   
}

 

重点是要实现一个这个类PackageInstallObserver，另外要注意import android.content.pm.……的那些包一定要导入。android.mk文件如下

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)

LOCAL_MODULE_TAGS := user

LOCAL_SRC_FILES := $(call all-subdir-java-files)

LOCAL_PACKAGE_NAME := InstallActivity
LOCAL_CERTIFICATE := platform

include $(BUILD_PACKAGE)

重点是LOCAL_CERTIFICATE := platform要对

 

另外编译的时候有可能会报R.java类重复错误，把你工程下gen文件夹删除即可，不会影响编译，传说中会在别的地方自动生成^……

 

作为一个新手，研究了四天无果，网上苦苦追寻无果，最后还是再前辈的带领下看系统安装源代码得来。看来要学好android还是要会看源代码。卷毛大帝。

这个在2.1上编译通过可以用，后台安装可以实现，后台卸载也可以实现，可以和安卓市场一样了。希望大家不要用这个功能搞图谋不轨的事情。

 

现在把工程和apk传上来大家看看，这种方法看来也不是适用于每一个系统，android系统太不统一了，只能这样了。

工程和apk.zip

这个需要源码编译环境，就是要下载一个android系统的源码

有时候我们需要软件实现静默安装，但是Android并未提供相应的API，然而我们知道命令行安装android的时候是不会提示用户的，所有要实现这个功能，我们就可以从执行命令行的方式实现。android提供的安装命令是

pm install package
ps : pm install /sdcard/android.apk

?

 

但是执行这个命令需要前提条件，需要是系统级应用或者具有ROOT权限。我们先介绍通过ROOT权限的方式执行。

1,通过获取ROOT权限静默安装APK
看代码：

new Thread() {
    public void run() {
    Process process = null;
    OutputStream out = null;
    InputStream in = null;
    try {
    // 请求root
    process = Runtime.getRuntime().exec("su");
    out = process.getOutputStream();
    // 调用安装
    out.write(("pm install -r " + currentTempFilePath + "\n").getBytes());
    in = process.getInputStream();
    int len = 0;
    byte[] bs = new byte[256];
    while (-1 != (len = in.read(bs))) {
    String state = new String(bs, 0, len);
    if (state.equals("Success\n")) {
       //安装成功后的操作
         }
       }
    } catch (IOException e) {
        e.printStackTrace();
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        try {
            if (out != null) {
                out.flush();
                out.close();
            }
            if (in != null) {
                in.close();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
  }
}.start();

 

当然也可以通过NDK实现，代码就不放了。

第二种方式，同样是通过pm命令实现，不用请求ROOT，但是需要系统的签名。这里附上模拟器的的签名，用这个签名的APK安装在模拟器上可以实现不请求ROOT而静默安装的效果。

?

//首先在manifest标签加入属性
android:sharedUserId="android.uid.system"

new Thread() {
    public void run() {
    Process process = null;
    InputStream in = null;
    try {
    // 请求root
    process = Runtime.getRuntime().
 exec("pm install -r " + currentTempFilePath + "\n");
    in = process.getInputStream();
    int len = 0;
    byte[] bs = new byte[256];
    while (-1 != (len = in.read(bs))) {
    String state = new String(bs, 0, len);
    if (state.equals("Success\n")) {
       //安装成功后的操作
         }
       }
    } catch (IOException e) {
        e.printStackTrace();
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        try {
            if (in != null) {
                in.close();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
  }
}.start();

通常情况下，android是没有提供静默方式的上层接口，我们需要在android源代码下来调用这个隐藏的接口来完成静默安装。
最重要的就是参考android系统目录下的packages/apps/PackageInstaller，
当中有两个文件 PackageInstallerActivity.java,InstallAppProgress.java ,前者就是我们通常看到的带有提示对话框的安装应用程序，后者是点确定安装后调用的intent。
现提供一个静默安装的关键类，该类在android2.2下成功编译, 其中通过循环调用接口instatllBatch则可实现批量安装
当然最后的应用程序别忘记添加权限

    <uses-permission android:name="android.permission.INSTALL_PACKAGES" />
    <uses-permission android:name="android.permission.DELETE_PACKAGES" />
    <uses-permission android:name="android.permission.CLEAR_APP_CACHE" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
