Using Intent.createChooser and getting error: Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag

Question

我想通过服务 class 中的选项打开共享。它在 Android 7 中工作正常，但在 8+ OS 中它开始显示

android.util.AndroidRuntimeException: Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?

我也已将此标志添加到我的 Intent 中，但它仍然显示相同的错误。

有没有其他方法可以通过服务 class 中的选项打开共享？

                    Intent i = new Intent(Intent.ACTION_SEND);
                    i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    i.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
                    i.putExtra(Intent.EXTRA_STREAM, rasta);  //rasta -> Uri obj
                    i.setType("image/*");
                    getApplicationContext().startService(Intent.createChooser(i,"Share karna..."));

Intent.createChooser 创建一个 Intent，因此您需要在那个意图上设置 FLAG_ACTIVITY_NEW_TASK 标志，例如，

                    Intent i = new Intent(Intent.ACTION_SEND);
                    i.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
                    i.putExtra(Intent.EXTRA_STREAM, rasta);  //rasta -> Uri obj
                    i.setType("image/*");
                    Intent chooserIntent = Intent.createChooser(i,"Share karna...");
                    chooserIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    getApplicationContext().startActivity(chooserIntent);

您还调用了 startService 而不是 startActivity - 请务必更正该错误。
