Android quick uninstall third-party applications

1. required permissions:
<Uses-permission android: name = "com. android. launcher. permission. READ_SETTINGS"/>
2. Obtain all applications
Public List <ResolveInfo> getAllPagckage (Context context)
{
PackageManager pm = context. getPackageManager ();

Intent mainIntent = new Intent (Intent. ACTION_MAIN, null );
MainIntent. addCategory (Intent. CATEGORY_LAUNCHER );
// Obtain all the ResolveInfo objects through the query.
List <ResolveInfo> resolveInfoList = pm. queryIntentActivities (
MainIntent, PackageManager. GET_GIDS );
// Sort the call system by name
Collections. sort (resolveInfoList,
New ResolveInfo. DisplayNameComparator (pm ));
Return resolveInfoList;
}
3. filter out third-party applications
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 );
// Third-party applications
If (resolveInfo. activityInfo. applicationInfo. flags & ApplicationInfo. FLAG_SYSTEM) <= 0)
{
List. add (resolveInfo );
}
}
}
}
4. Uninstall
(Note: 1. Both methods are supported; 2. appPackage is resolveInfo. activityInfo. packageName)
Public void uninstallApp (Context context, String appPackage)
{
Uri packageURI = Uri. parse ("package:" + appPackage );
// Custom uninstall
// Intent uninstallIntent = new Intent (Intent. ACTION_DELETE,
// PackageURI );
// (Activity) context). startActivityForResult (uninstallIntent, 0 );
// Call the system's own uninstall operation to uninstall it
Intent uninstallIntent = new Intent (
Settings. ACTION_APPLICATION_DETAILS_SETTINGS, packageURI );
Context. startActivity (uninstallIntent );
}
