从 Activity 上下文外部调用 startActivity() 需要 FLAG_ACTIVITY_NEW_TASK 标志 [重复]

Question

我在 android 中创建了表情符号键盘，但我可以在键盘视图中添加共享此应用程序按钮。

这里是我的点击分享方法。

public void shareapp() {
    String shareText = getResources().getString(R.string.share_text);
    Intent sendIntent = new Intent();
    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");
    getApplication().getApplicationContext().startActivity(chooseIntent);
}

但是在单击共享应用按钮时发生错误 请参阅错误：

谁能帮我解决我的问题？

在开始这样的活动时，您需要为您的意图设置标志

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

您出于错误的意图设置了标志。
