android 10.0录制屏幕报错. Media projections require a foreground service of type ServiceInfo.FOREGROUND_SERVICE
报错原因
- Android10.0以上的录制屏幕需要获取到FOREGROUND_SERVICE权限
- Android10.0以上实例化mediaProjection需要在service里进行
- Android10.0以上录制屏幕需要添加notification,提醒用户该app正在录制屏幕
Caused by: java.lang.SecurityException: Media projections require a foreground service of type ServiceInfo.FOREGROUND_SERVICE_TYPE_MEDIA_PROJECTION
报错解决 (这里默认你已经写好了正常的录制屏幕流程)
1.在AndroidManifest.xml内的service添加foregroundServiceType
android:foregroundServiceType="mediaProjection"
2,在申请录屏幕权限后的返回数据onActivityResult内对sdk进行判断,并实现startForegroundService。
这样我们就可以在service内进行初始化mediaProjection了
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
screenRecordService.setMediaProject(MediaProject); //将MediaProject传进service里,这个medieaProject应该为 null
screenRecordService.setMediaProjectionManager(MediaProjectionManager); //将mediaProjectionManager传进service里,这个manager你应该已经在`ServiceConnection`时实例化好了()
Intent service = new Intent(this, ScreenRecordService.class);
service.putExtra("code", resultCode);
service.putExtra("data", data);
startForegroundService(service);
}
}
调过startForegroundService会执行service的 onStartCommand 方法,之后我们就可以在service里进行实例化 MediaProject了。
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
createNotificationChannel(); //创建通知栏,你正在录屏
Bundle bundle = intent.getExtras();
MediaProject = mediaProjectionManager.getMediaProjection( bundle.getInt("code",-1), Objects.requireNonNull(intent.getParcelableExtra("data")));
if(null != mOnStartCommandListener){
mOnStartCommandListener.finished(mediaProjection!=null);
}
} return START_STICKY;
}
3.构造Notification
private void createNotificationChannel() {
Notification.Builder builder = new Notification.Builder(this.getApplicationContext()); //获取一个Notification构造器
Intent nfIntent = new Intent(this, TutorW2Activity.class); //点击后跳转的界面,可以设置跳转数据
builder.setContentIntent(PendingIntent.getActivity(this, 0, nfIntent, 0)) // 设置PendingIntent
.setLargeIcon(BitmapFactory.decodeResource(this.getResources(), R.mipmap.ic_launcher)) // 设置下拉列表中的图标(大图标)
//.setContentTitle("SMI InstantView") // 设置下拉列表里的标题
.setSmallIcon(R.mipmap.ic_launcher) // 设置状态栏内的小图标
.setContentText("is running......") // 设置上下文内容
.setWhen(System.currentTimeMillis()); // 设置该通知发生的时间
/*以下是对Android 8.0的适配*/
//普通notification适配
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
builder.setChannelId("notification_id");
}
//前台服务notification适配
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationManager notificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
NotificationChannel channel = new NotificationChannel("notification_id", "notification_name", NotificationManager.IMPORTANCE_LOW);
notificationManager.createNotificationChannel(channel);
}
Notification notification = builder.build(); // 获取构建好的Notification
notification.defaults = Notification.DEFAULT_SOUND; //设置为默认的声音
startForeground(110, notification);
}
