android - Intent 卸载用户应用程序android

Question

我的应用程序在 ListView 中显示所有用户应用程序，我想将用户带到可以单击卸载该应用程序的屏幕。但是，我使用的代码会打开信息屏幕大约 1/4 秒，然后将用户带回应用程序。我哪里错了？？

ListView listView = (ListView) findViewById(R.id.mobile_list);
listView.setAdapter(adapter);
listView.setOnItemClickListener(new OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        String packageName = results.get(position);
        Intent intent = new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        intent.setData(Uri.parse("package:" + packageName));
        startActivity(intent);
    }
});

我想将用户直接带到询问“您确定要卸载 .apk 吗？”的消息

请引用以下代码:

String app_pkg_name = "com.example.app";
int UNINSTALL_REQUEST_CODE = 1;

Intent intent = new Intent(Intent.ACTION_UNINSTALL_PACKAGE);  
intent.setData(Uri.parse("package:" + app_pkg_name));  
intent.putExtra(Intent.EXTRA_RETURN_RESULT, true);
startActivityForResult(intent, UNINSTALL_REQUEST_CODE);
