Service Intent must be explicit的解决方法

今天遇到如标题问题，查阅资料：http://blog.android-develop.com/2014/10/android-l-api-21-javalangillegalargumen.html

 /***
     * Android L (lollipop, API 21) introduced a new problem when trying to invoke implicit intent,
     * "java.lang.IllegalArgumentException: Service Intent must be explicit"
     *
     * If you are using an implicit intent, and know only 1 target would answer this intent,
     * This method will help you turn the implicit intent into the explicit form.
     *
     * Inspired from SO answer: http://stackoverflow.com/a/26318757/1446466
     * @param context
     * @param implicitIntent - The original implicit intent
     * @return Explicit Intent created from the implicit original intent
     */
    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;
    }

一个转换方法，如下方法调用：

 private void startMyIntentService() {
         Intent startServiceIntent = new Intent("com.soyoungboy.intentservice");
         Bundle bundle = new Bundle();
         bundle.putString("param", "oper1");
         startServiceIntent.putExtras(bundle);
         startService(createExplicitFromImplicitIntent(this,startServiceIntent));
     }

就可以了
