服务的androidmanifest.xml
<service
android:name=".myservice"
android:enabled="true"
android:exported="true"></service>
在 activity 中的调用
Intent intent = new Intent();
intent.setComponent(new ComponentName("com.zxb.service", "com.zxb.service.myservice"));
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);
Log.d("开始服务", "onResume: com.zxb.service");
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
Log.d("开始服务", "onResume: 前台服务");
startForegroundService(intent);
} else {
Log.d("开始服务", "onResume: 后台服务");
startService(intent);
}
