android - 卸载包

Question

我想自己卸载我的应用程序，但它在 SerialVersionUID 上抛出 NullPointerException不知道这里出了什么问题？

public void UnInstallApplication() throws NameNotFoundException 
{
    Intent intent = new Intent(Intent.ACTION_DELETE, Uri.fromParts("package",
            getPackageManager().getPackageInfo("com.XXX.XXX", 0).packageName,null));
            startActivity(intent);
}

或者我在下面使用了这一行(在函数中插入了包名)但结果相同!

Intent uninstallIntent = new Intent(Intent.ACTION_DELETE);
    uninstallIntent.setData(Uri.parse("package:" + packagename));
    startActivity(uninstallIntent); 

Answer 1

使用这段代码:

Uri packageURI = Uri.parse("package:your.packge.name");
Intent uninstallIntent = new Intent(Intent.ACTION_DELETE, packageURI);
startActivity(uninstallIntent);
