    sendIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    sendIntent.setAction(Intent.ACTION_SEND);
    sendIntent.putExtra(Intent.EXTRA_TEXT, shareText + "https://play.google.com/store/apps/details?id=" + getPackageName());
    sendIntent.setType("text/plain");
    Intent chooseIntent = Intent.createChooser(sendIntent, "Share this via");

any one can help me to solve my problems?

You need to call `addFlags()` on the `chooseIntent` that you get back from `createChooser()`. — David Wasser, Jan 12 '18 at 17:59

You need to set flag to your intent when starting activity like this

Intent chooseIntent = Intent.createChooser(sendIntent, "Share this via");
chooseIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
getApplication().getApplicationContext().startActivity(chooseIntent);

You setting a flag on wrong intent.

Both methods setFlags() and addFlags() can be used to set up the flags. The only difference is that the setFlags() method removes previously added flags. https://stackoverflow.com/questions/6664189/androidwhat-is-difference-between-setflags-and-addflags-for-intent – Valeriy Katkov Jan 11 '18 at 08:37
