service intent must be explicit:intent问题的解决

Android 5.0以上不允许隐式启动服务，所以回报这个错误！

解决办法一：

将原启动方式更改为如下启动方式：

 final Intent intent = new Intent();
 intent.setAction("com.example.user.firstapp.FIRST_SERVICE");
 intent.setPackage(this.getPackageName());
 bindService(intent,conn,Service.BIND_AUTO_CREATE);

解决办法二：

可以将隐式调用更改为显示调用，先定义一个函数：

  public static Intent createExplicitFromImplicitIntent(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;
     }

       下一步：

将此函数在原调用service的地方调用即可：

 final Intent intent = new Intent();
 intent.setAction("com.example.user.firstapp.FIRST_SERVICE");
 final Intent eintent = new Intent(createExplicitFromImplicitIntent(this,intent));
 bindService(eintent,conn, Service.BIND_AUTO_CREATE);
