  • 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:

    1 private void startMyIntentService() {
    2         Intent startServiceIntent = new Intent("com.soyoungboy.intentservice");
    3         Bundle bundle = new Bundle();
    4         bundle.putString("param", "oper1");
    5         startServiceIntent.putExtras(bundle);
    6         startService(createExplicitFromImplicitIntent(this,startServiceIntent));
    7     }

    就可以了
