[英]Getting an Error : app not found, when i click on the homescreen shortcut in android App
[英]shortcut not opening app on android homescreen
我已经在Android设备上安装了一些应用程序,并且我开发了一个代码来为其创建快捷方式,它们都可以与一个应用程序分开工作,但是如果我在主屏幕上手动拖动该应用程序,它将非常有效。下一个代码是我用来创建快捷方式的代码
try
{
//Log.i("shortcut method in androidhelper start","in the shortcutapp on create method ");
boolean flag =false ;
int app_id=-1;
PackageManager p = getPackageManager();
Intent i = new Intent(Intent.ACTION_MAIN);
i.addCategory(Intent.CATEGORY_LAUNCHER);
List<ResolveInfo> res =p.queryIntentActivities( i,0);
//System.out.println("the res size is: "+res.size());
for(int k=0;k<res.size();k++)
{
//Log.i("","the application name is: "+res.get(k).activityInfo.loadLabel(p));
if(res.get(k).activityInfo.loadLabel(p).toString().equals("Kortext")){
flag = true;
app_id = k;
break;
}
}
if(flag)
{
ActivityInfo ai = res.get(app_id).activityInfo;
Intent shortcutIntent = new Intent();
shortcutIntent.setClassName(ai.packageName, ai.name);
shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
shortcutIntent.addCategory(Intent.ACTION_PICK_ACTIVITY);
Intent intent = new Intent();
intent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
// Sets the custom shortcut's title
intent.putExtra(Intent.EXTRA_SHORTCUT_NAME, "Kortext");
BitmapDrawable bd=(BitmapDrawable)(res.get(app_id).activityInfo.loadIcon(p).getCurrent());
Bitmap newbit;
newbit=bd.getBitmap();
intent.putExtra(Intent.EXTRA_SHORTCUT_ICON, newbit);
intent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
sendBroadcast(intent);
}
else
{
// throw new UserException(UserException.KErrGeneral,"Application not found");
}
}
catch(ActivityNotFoundException e)
{
e.printStackTrace();
//throw new UserException(UserException.KErrGsmRRNoActivityOnRadioPath,e.getMessage());
}
catch(Exception e)
{
e.printStackTrace();
//throw new UserException(UserException.KErrGeneral,e.getMessage());
}
有任何想法吗?
我弄清楚了,我还必须将意图更改为新的Intent(Intent.ACTION_MAIN);
