[英]How to check if application is uninstalled from android/ Iphone device
[英]How to get action that android application is trying removed/uninstalled from device
當用戶想要從Android設備卸載應用程序時,我想要該應用程序的用戶卸載按鈕單擊事件。
我正在從設備中刪除應用程序的事件,但我想在刪除應用程序之前顯示彈出窗口。 我正在嘗試實現與“App Lock”應用程序相同的功能。
這是我通過廣播接收器獲取應用程序刪除事件的代碼。 但是關於卸載按鈕單擊或彈出單擊之前,我完全是空白。 請指導我正確的方向。
提前致謝。
public class MainActivity extends Activity {
CustomBroadcastReceiver mApplicationsReceiver;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mApplicationsReceiver=new CustomBroadcastReceiver();
IntentFilter filter = new IntentFilter(Intent.ACTION_PACKAGE_ADDED);
filter.addAction(Intent.ACTION_PACKAGE_REMOVED);
filter.addAction(Intent.ACTION_PACKAGE_CHANGED);
filter.addAction(Intent.ACTION_PACKAGE_ADDED);
filter.addAction(Intent.ACTION_PACKAGE_REPLACED);
filter.addAction(Intent.ACTION_PACKAGE_RESTARTED);
filter.addAction(Intent.ACTION_PACKAGE_VERIFIED);
filter.addAction(Intent.ACTION_PACKAGE_INSTALL);
filter.addAction(Intent.ACTION_PACKAGE_FIRST_LAUNCH);
filter.addAction(Intent.ACTION_DELETE);
filter.addAction(Intent.ACTION_DEFAULT);
filter.addDataScheme("package");
registerReceiver(mApplicationsReceiver, filter);
}
}
public class CustomBroadcastReceiver extends BroadcastReceiver {
/**
* This method captures the event when a package has been removed
*/
@Override
public void onReceive(Context context, Intent intent)
{
System.out.println("Hello from CustomBroadcastReceiver");
if (intent != null) {
String action = intent.getAction();
System.out.println("L1123 : "+action);
if (action.equals(intent.ACTION_PACKAGE_REMOVED)) {
//Log the event capture in the log file ...
System.out.println("The package has been removed");
}
}
}
}

請嘗試通過ActivityManager
獲取任務中的頂級ActivityManager
,並檢查它是否是卸載活動。
核心代碼:
ComponentName topActivity = mActivityManager.getRunningTasks(1).get(0).topActivity;
String packageName = topActivity.getPackageName();
String className = topActivity.getClassName();
Log.v(TAG, "packageName" + packageName);
Log.v(TAG, "className" + className);
if ("com.android.packageinstaller".equals(packageName)
&& "com.android.packageinstaller.UninstallerActivity".equals(className)) {
//Do anything you want here
}
