Android实现快捷卸载第三方应用

jopen 11年前

1、需要的权限：

 
    <uses-permission android:name="com.android.launcher.permission.READ_SETTINGS" />

2、获取所有应用：

 
    public List<ResolveInfo> getAllPagckage(Context context)        {        PackageManager pm = context.getPackageManager();                 Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);        mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);        // 通过查询，获得所有ResolveInfo对象.        List<ResolveInfo> resolveInfoList = pm.queryIntentActivities(        mainIntent, PackageManager.GET_GIDS);        // 调用系统排序，根据name排序        Collections.sort(resolveInfoList,        new ResolveInfo.DisplayNameComparator(pm));        return resolveInfoList;        }

3、过滤出第三方应用：

 
    private void filterPackage(List<ResolveInfo> allPackageList)        {        if (!allPackageList.isEmpty())        {        list.clear();        int size = allPackageList.size();        ResolveInfo resolveInfo = null;        for (int i = 0; i < size; i++)        {        resolveInfo = allPackageList.get(i);        // 第三方应用        if((resolveInfo.activityInfo.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) <= 0)        {        list.add(resolveInfo);        }        }        }        }

4、卸载：
(注：1、两种方式均可；2、appPackage为resolveInfo.activityInfo.packageName)
 
public void uninstallApp(Context context, String appPackage)    {    Uri packageURI = Uri.parse("package:" + appPackage);            //自定义卸载    // Intent uninstallIntent = new Intent(Intent.ACTION_DELETE,    // packageURI);    //((Activity)context).startActivityForResult(uninstallIntent, 0);            //调用系统自带卸载操作进行卸载    Intent uninstallIntent = new Intent(    Settings.ACTION_APPLICATION_DETAILS_SETTINGS, packageURI);    context.startActivity(uninstallIntent);    }
