（转）Android 应用的安装和卸载

1.普通的应用安装和卸载

/* 安装apk */
public static void installApk(Context context, String fileName) {
    Intent intent = new Intent();
    intent.setAction(Intent.ACTION_VIEW);
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    intent.setDataAndType(Uri.parse("file://" + fileName),"application/vnd.android.package-archive");
    context.startActivity(intent);
}

/* 卸载apk */
public static void uninstallApk(Context context, String packageName) {
    Uri uri = Uri.parse("package:" + packageName);
    Intent intent = new Intent(Intent.ACTION_DELETE, uri);
    context.startActivity(intent);
}

当应用安装或卸载成功后，系统会发送相应的广播

监听系统发出的安装广播

在安装和卸载完后，android系统会发一个广播

android.intent.action.PACKAGE_ADDED（安装）

android.intent.action.PACKAGE_REMOVED（卸载）

我们可以监听这两个广播，来进行相应的处理

public class MonitorSysReceiver extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent){
        //接收安装广播
        if (intent.getAction().equals("android.intent.action.PACKAGE_ADDED")) {
            //TODO
        }
        //接收卸载广播
        if (intent.getAction().equals("android.intent.action.PACKAGE_REMOVED")) {
            //TODO
        }
    }
}

在AndroidMainFest.xml中，我们需要注册该广播

<receiver android:name=".MonitorSysReceiver">
          <intent-filter>
           <action android:name="android.intent.action.PACKAGE_ADDED" />
           <action android:name="android.intent.action.PACKAGE_REMOVED" />
          </intent-filter>
</receiver>

2.Android的静默安装和卸载

Android的静默安装和卸载，需要将应用注册成系统用户组，并且需要在系统源码下编译才行。

android:sharedUserId="android.uid.system"

还需要相应的权限

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

报红的话，clean一下就行了

静默安装

安装方法：

String fileName = Environment.getExternalStorageDirectory() + File.separator + "baidu"+File.separator +"UC.apk";
Uri uri = Uri.fromFile(new File(fileName));
int installFlags = 0;
PackageManager pm = getPackageManager();
try {
    PackageInfo pi = pm.getPackageInfo("com.UCMobile",PackageManager.GET_UNINSTALLED_PACKAGES);
    if(pi != null) {
        installFlags |= PackageManager.INSTALL_REPLACE_EXISTING;
    }
} catch (Exception e) {
    Log.e("exception",e.toString());
}
MyPakcageInstallObserver observer = new MyPakcageInstallObserver();
pm.installPackage(uri, observer, installFlags, "com.UCMobile");

安装回调

/*静默安装回调*/
class MyPakcageInstallObserver extends IPackageInstallObserver.Stub{

    @Override
    public void packageInstalled(String packageName, int returnCode) {
        if (returnCode == 1) {
            Log.e("DEMO","安装成功");
            new ToastThread(InstallActivity.this,"安装成功").start();
        }else{
            Log.e("DEMO","安装失败,返回码是:"+returnCode);
            new ToastThread(InstallActivity.this,"安装失败,返回码是:"+returnCode).start();
        }
    }
}

静默卸载：

PackageManager pm = ParentManagementSettings.this.getPackageManager();
IPackageDeleteObserver observer = new MyPackageDeleteObserver();
pm.deletePackage("com.readboy.microclassphone", observer, 0);

/**
 * 应用静默删除回调
 * @author 1
 *
 */
class MyPackageDeleteObserver extends IPackageDeleteObserver.Stub {
    @Override
    public void packageDeleted(String packageName, int returnCode) {
        if (returnCode == 1) {
            Log.e("DEMO","success...");
        }else{
            Log.e("DEMO","fail code:"+returnCode);
        }
    }
}

备注：

  根据APK的path路径，查看APK的包名

PackageManager pm2=getActivity().getPackageManager();
PackageInfo info=pm2.getPackageArchiveInfo(files[i].getPath(), 0);
Log.e("DEMO", "infoName"+info.packageName);
packageNameString=info.packageName;
