在我的应用程序中，我使用 SharCompat 来获取我想要共享内容的应用程序列表。我在列表中有 twitter 应用程序。当我在设备中访问 twitter 应用程序时。我遇到了以下异常。

要打开应用程序列表以共享内容，我使用了以下代码

ShareCompat.IntentBuilder builder = ShareCompat.IntentBuilder.from(Myactivity.this);
builder.setType("text/plain");
Intent i = builder.getIntent();
startActivity(Intent.createChooser(i, "test"));

打开 Twitter 应用程序的签名页面时出现以下异常

这段代码对我有用： 

Intent shareIntent = ShareCompat.IntentBuilder
                .from(LocalCharadeActivity.this).setType("text/plain")
                .setText("lalal").getIntent();

startActivity(shareIntent);
