使用onclick強制關閉從設備卸載應用程序？

Question

這是我的代碼，用於調用卸載程序Intent以獲取通過文本字段輸入的包名稱。

的問題是，當我按下button我的應用程序強制關閉，下面是我的代碼 -

public void uninstall(View view) { 
    String packagename = seturl.getText().toString(); 
    Uri packageUri = Uri.parse(packagename); 
    Intent uninstallIntent = new Intent(Intent.ACTION_UNINSTALL_PACKAGE, 
      packageUri); 
    startActivity(uninstallIntent); 
}

問題是軟件包的名稱，它不是找到合適的人，先硬包裝（如果你的包名是com.android.yourpakgenamehere）名稱，看看它是否工作！

Uri packageURI = Uri.parse("package:com.android.yourpakgenamehere"); // see here how i used it 
Intent uninstallIntent = new Intent(Intent.ACTION_DELETE, packageURI); 
startActivity(uninstallIntent); 

然後你就可以得到它這樣，更換鐵桿名字，

全球對類：

public static String PACKAGE_NAME; 

然後..

@Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     PACKAGE_NAME = getApplicationContext().getPackageName(); 
    } 

You can then access it via `Main.PACKAGE_NAME`. // considering Activity name as Main 

現在你有包名，所以這樣做;

Uri packageUri = Uri.parse("package:"+ActivityYouUse.PACKAGE_NAME); 

無論如何，當你把它放在遊戲商店你能改變你的包名嗎？因此，即使該字符串值爲靜態
