java - API 23 (Android 6.0.1) 应用内计费 : Service Intent must be explicit: Intent

Question

我一直在四处寻找，这似乎是一个与 Android L 相关的错误，显然已经使用我已有的代码解决了。

当我尝试调用 bindService 时，我得到:

Fatal Exception: java.lang.RuntimeException: Unable to resume activity {MyActivity}: java.lang.IllegalArgumentException: Service Intent must be explicit: Intent { act=com.android.vending.billing.InAppBillingService.BINL }

这是导致崩溃的代码 fragment :

    final Intent serviceIntent = new Intent("com.android.vending.billing.InAppBillingService.BIND");
    serviceIntent.setPackage("com.android.vending");
    activity.bindService(serviceIntent, this, Context.BIND_AUTO_CREATE);

它只发生在 Android 6.0.1 和我在 23 中的 gradle 目标上，我似乎无法理解 API 23 上的问题...

如果您正在使用 IabHelper 类。转到IabHelper.java 中的startSetup 方法。添加以下代码

Intent serviceIntent = new Intent("com.android.vending.billing.InAppBillingService.BIND");
        if (!mContext.getPackageManager().queryIntentServices(serviceIntent, 0).isEmpty()) {
            // service available to handle that Intent
            serviceIntent.setPackage("com.android.vending");

            mContext.bindService(serviceIntent, mServiceConn, Context.BIND_AUTO_CREATE);
        }
        else {
            // no service available to handle that Intent
            if (listener != null) {
                listener.onIabSetupFinished(
                        new IabResult(BILLING_RESPONSE_RESULT_BILLING_UNAVAILABLE,
                                "Billing service unavailable on device."));
            }
        }

此方法将帮助您将隐式 Intent 转换为显式形式。灵感来自 SO 答案:https://stackoverflow.com/a/26318757/1446466bindServiceConn() 方法正在创建服务。

 * @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;
}



  protected void bindServiceConn() {
//call this method 
        Intent intent = createExplicitFromImplicitIntent(context.getApplicationContext(), new Intent("com.android.vending.billing.InAppBillingService.BIND"));
        context.bindService(intent, mServiceConn, Context.BIND_AUTO_CREATE);
    }

protected void unbindServiceConn() {
    context.unbindService(mServiceConn);

    context=null;
}
