Question

当我致电ACTION_SEND时，这会显示一个共享框，但活动已关闭并显示错误

try {
            SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
            String link = preferences.getString("speed", "");
            Intent i = new Intent(Intent.ACTION_SEND);
            i.setType("text/plain");
            i.putExtra(Intent.EXTRA_SUBJECT, "subject");
            String sAux = "\nText:\n\n";
            sAux = sAux + link + "\n\n";
            i.putExtra(Intent.EXTRA_TEXT, sAux);
            startActivity(Intent.createChooser(i, "Share Link"));
        } catch (Exception e) {
            e.toString();
        }

我已使用此配置活动：

<activity android:name=".Settings" android:screenOrientation="portrait" >
            <intent-filter>
                <action android:name="android.intent.action.SEND" />
                <category android:name="android.intent.category.DEFAULT" />
                <data android:mimeType="text/plain" />
            </intent-filter>
        </activity>

完整的错误代码是：

在第56行，我有：startActivity(Intent.createChooser(i, "Share Link"));

活动已关闭，但我仍然看到一个共享框。

感谢您的帮助，如果您需要其他信息写评论

解决了我在onPause中完成（）所以当共享应用程序时，请暂停并完成...

Answer 2

我有同样的错误。就我而言，活动没有关闭，但是错误在错误日志中。这仅发生在Android 7上。我可以通过使用具有以下设置的Intent来摆脱此错误：

    Intent share = new Intent(Intent.ACTION_SEND);
    share.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
    share.setDataAndType(new Uri.Builder().build(), "message/rfc822");
    share.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION|Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
    share.putExtra(Intent.EXTRA_SUBJECT, "Here the subject");
    share.putExtra(Intent.EXTRA_TEXT, "https://www.example.com/share?r=123456789");

    startActivity(Intent.createChooser(share, "Create..."));

在Android 5.1、7和9上进行了测试。

使用grantUriPermission错误的ACTION_SEND崩溃活动
