如何解决Android 5.0中出现的警告:Service Intent must be explicit

有些时候我们使用Service的时需要采用隐私启动的方式,但是Android 5.0一出来后,其中有个特性就是Service Intent  must be explitict,也就是说从Lollipop开始,service服务必须采用显示方式启动。
而android源码是这样写的(源码位置:sdk/sources/android-21/android/app/ContextImpl.java):

  1. private void validateServiceIntent(Intent service) {
  2. if (service.getComponent() == null && service.getPackage() == null) {
  3. if (getApplicationInfo().targetSdkVersion >= Build.VERSION_CODES.LOLLIPOP) {
  4. IllegalArgumentException ex = new IllegalArgumentException(
  5. "Service Intent must be explicit: " + service);
  6. throw ex;
  7. } else {
  8. Log.w(TAG, "Implicit intents with startService are not safe: " + service
  9. + " " + Debug.getCallers(2, 3));
  10. }
  11. }
  12. }

既然,源码里是这样写的,那么这里有两种解决方法:

1、设置Action和packageName:

参考代码如下:

  1. Intent mIntent = new Intent();
  2. mIntent.setAction("XXX.XXX.XXX");//你定义的service的action
  3. mIntent.setPackage(getPackageName());//这里你需要设置你应用的包名
  4. context.startService(mIntent);

此方式是google官方推荐使用的解决方法。

2、将隐式启动转换为显示启动:--参考地址:http://*.com/a/26318757/1446466

  1. public static Intent getExplicitIntent(Context context, Intent implicitIntent) {
  2. // Retrieve all services that can match the given intent
  3. PackageManager pm = context.getPackageManager();
  4. List<ResolveInfo> resolveInfo = pm.queryIntentServices(implicitIntent, 0);
  5. // Make sure only one match was found
  6. if (resolveInfo == null || resolveInfo.size() != 1) {
  7. return null;
  8. }
  9. // Get component info and create ComponentName
  10. ResolveInfo serviceInfo = resolveInfo.get(0);
  11. String packageName = serviceInfo.serviceInfo.packageName;
  12. String className = serviceInfo.serviceInfo.name;
  13. ComponentName component = new ComponentName(packageName, className);
  14. // Create a new intent. Use the old one for extras and such reuse
  15. Intent explicitIntent = new Intent(implicitIntent);
  16. // Set the component to be explicit
  17. explicitIntent.setComponent(component);
  18. return explicitIntent;
  19. }

调用方式如下:

  1. Intent mIntent = new Intent();
  2. mIntent.setAction("XXX.XXX.XXX");
  3. Intent eintent = new Intent(getExplicitIntent(mContext,mIntent));
  4. context.startService(eintent);
