隐式意图卸载应用程序？ [英] Implicit intent to uninstall application?

问题描述

我想有一个onclicklistener调用的意图，卸载应用程序，通过让意图调用默认的卸载程序的活动，从应用程序设置。我发现<一href="http://developer.android.com/reference/android/content/Intent.html#ACTION_UNINSTALL_PACKAGE">here 我可以卸载使用ACTION_UNINSTALL_PACKAGE，com.packageXYXY，这似乎是我要找的一个应用程序。 不过，我不能确定如何调用此。我已经试过如下：

I am trying to have an onclicklistener call an intent to uninstall an app, by having the intent call the default "uninstall app" activity from the applications settings. I have found here that I can uninstall an app using ACTION_UNINSTALL_PACKAGE, com.packageXYXY, which seems to be what I'm looking for. However, I am unsure how to call this. I have tried the following:

public void onClick(DialogInterface dialog, int which) {
                Uri packageURI = Uri.parse("package:com.packageName");
                Intent uninstallIntent = new Intent(Intent.ACTION_UNINSTALL_PACKAGE, packageURI);
                startActivity(uninstallIntent);

但语法是错误的。已经尝试了一些调用此不同的方式，和也有点卡住。不知道如何调用此。感谢您的帮助。

but the syntax is wrong. Have tried a number of different ways of calling this, and am kind of stuck. Not sure how to call this. Thanks for your help.

推荐答案

首先，请注意ACTION_UNINSTALL_PACKAGE只有菱到Android-14（即冰激凌三明治的Andr​​oid 4.0）。这就是说，下面的code对我的作品：

First of all, note that the ACTION_UNINSTALL_PACKAGE is only availible to android-14 (i.e. Ice Cream Sandwich, Android 4.0). That said, the following code works for me:

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
import android.view.View;
import android.net.Uri;
import android.content.Intent;

public class TestActivity extends Activity
{
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        TextView view = (TextView)findViewById(R.id.test_view);
        view.setOnClickListener(new View.OnClickListener(){
          public void onClick(View view){
            Uri packageUri = Uri.parse("package:org.klnusbaum.test");
            Intent uninstallIntent =
              new Intent(Intent.ACTION_UNINSTALL_PACKAGE, packageUri);
            startActivity(uninstallIntent);
          }
        });
    }
}

如果您希望能够做到这一点对所有版本的Andr​​oid平台，只是改变从 Intent.ACTION_UNINSTALL_PACKAGE 意图意图。 ACTION_DELETE 像@ goto10一样。

If you want to be able to do this on all versions of the android platform, just change the intent from Intent.ACTION_UNINSTALL_PACKAGE to Intent.ACTION_DELETE like @goto10 does.
