Question

我知道这是该板上的热门话题，但是该板上的建议和示例似乎不起作用，可能是因为它们再次更改了API28中的内容。我正在尝试共享相机拍摄的照片，但logcat显示不允许启动背景

24 23:30:48.870 1883-3164/system_process W/ActivityManager: Background start not allowed: service Intent { cmp=com.google.android.apps.photos/com.google.android.libraries.social.mediamonitor.BackgroundThreadNotifierIntentService (has extras) } to com.google.android.apps.photos/com.google.android.libraries.social.mediamonitor.BackgroundThreadNotifierIntentService from pid=7950 uid=10051 pkg=com.google.android.apps.photos startFg?=false

该项目是SDK

API 28

AndroidManifest是

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.REQUEST_COMPANION_USE_DATA_IN_BACKGROUND" />
<uses-permission android:name="android.permission.REQUEST_COMPANION_RUN_IN_BACKGROUND" />

MainActivity

        ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CAMERA,
            Manifest.permission.WRITE_EXTERNAL_STORAGE,
            Manifest.permission.READ_EXTERNAL_STORAGE,
            Manifest.permission.REQUEST_COMPANION_USE_DATA_IN_BACKGROUND,
            Manifest.permission.REQUEST_COMPANION_RUN_IN_BACKGROUND}, 1);

PhotoActivity

public class PhotoActivity extends AppCompatActivity

我尝试了三种在stackoverflow上找到的不同方法，但是所有这些方法在logcat中都显示相同的错误。

            if (false)
            {
                Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
                mediaScanIntent.setData(Uri.fromFile(photoFile));
                getApplicationContext().sendBroadcast(mediaScanIntent);
            }
            if (false)
            {
                MediaScannerConnection.scanFile(getApplicationContext(), new String[]{photoFile.getAbsolutePath()}, null, new MediaScannerConnection.OnScanCompletedListener()
                {
                    public void onScanCompleted(String path, Uri uri)
                    {
                        int exampleCodeDidNotShowWhatToDoHere = 1;
                    }
                });
            }

            MediaStore.Images.Media.insertImage(getApplicationContext().getContentResolver(),
                    photoFile.getAbsolutePath(), photoFile.getName(), null);
            getApplicationContext().sendBroadcast(new Intent(
                    Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile(photoFile)));

Intent.ACTION_MEDIA_SCANNER_SCAN_FILE不允许后台启动
