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
