Android L(API 21)-java.lang.IllegalArgumentException：服务意图必须明确

Android新版本-“ Lollipop”(API 21)带来了很多变化,但是如果您希望将应用程序定位到该API,则会附带一些价格.

当我们开始将应用程序适应新的API时,遇到的第一个问题就是IllegalArgumentException：服务意图必须明确

如果您遇到了问题,并且实际上打算以显式方式使用您的意图(这意味着在启动服务时,您期望准确地执行1个服务操作),这是一种将隐式变成->的快速解决方案.明确的：

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;
    }

那应该做.请随时发表评论,以获取有关此新问题的更多见解.

解决方法:

明确启动服务

intent = new Intent(context, Service.class);

或以隐式意图显式提供软件包

intent = new Intent("com.example.intent.ACTION");
intent.setPackage("com.example")
