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按钮。

这是我的点击共享方法。

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);
}

但点击共享应用按钮时会发生错误见错误：

任何人都可以帮我解决问题吗？

Answer 1

在开始像这样的活动

时，你需要为你的意图设置标志

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

您在错误的意图上设置了标记。

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