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):

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

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:

    Intent mIntent = new Intent();    mIntent.setAction("XXX.XXX.XXX");//你定义的service的action    mIntent.setPackage(getPackageName());//这里你需要设置你应用的包名    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://stackoverflow.com/a/26318757/1446466
    public static Intent getExplicitIntent(Context context, Intent implicitIntent) {            // Retrieve all services that can match the given intent            PackageManager pm = context.getPackageManager();            List<ResolveInfo> resolveInfo = pm.queryIntentServices(implicitIntent, 0);            // Make sure only one match was found            if (resolveInfo == null || resolveInfo.size() != 1) {                return null;            }            // Get component info and create ComponentName            ResolveInfo serviceInfo = resolveInfo.get(0);            String packageName = serviceInfo.serviceInfo.packageName;            String className = serviceInfo.serviceInfo.name;            ComponentName component = new ComponentName(packageName, className);            // Create a new intent. Use the old one for extras and such reuse            Intent explicitIntent = new Intent(implicitIntent);            // Set the component to be explicit            explicitIntent.setComponent(component);            return explicitIntent;        }
调用方式如下:
    Intent mIntent = new Intent();    mIntent.setAction("XXX.XXX.XXX");    Intent eintent = new Intent(getExplicitIntent(mContext,mIntent));    context.startService(eintent);
