我在我的应用中使用AdMob。我遵循了实现指南,横幅正确地显示和加载广告。我的MainActivity负责创建引用、构建AdRequest并显示横幅,以及暂停、恢复和销毁AdView。每次AdRequest被加载时,在Activity的onStop()被调用时,将创建以下异常:
6706-6706/com.rocca.controlloSpese E/ActivityThread﹕ Activity com.rocca.controlloSpese.MainActivity has leaked ServiceConnection com.google.android.gms.common.b@52b1cc3c that was originally bound here

接着是这些信息:

如果AdRequest没有被构建和加载,就不会发生这种情况。我在onCreate()中设置了我的IABHelper,如果用户没有购买我的“去广告”sku,那么就会显示广告。这是我用来加载广告的代码:
private void showAds() {
int adresult = GooglePlayServicesUtil.isGooglePlayServicesAvailable(MainActivity.this);
if (adresult == ConnectionResult.SUCCESS) {
//if possible, show ads
AdRequest adRequest = new AdRequest.Builder()
.addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
.addTestDevice("C144E9DA02EA7B26F74ED2C231F31D38")
.addTestDevice("93BABD84466B8C1EF529D2FB39D1ACE8")
.addTestDevice("BEAA738068664AE9BBF673E37A782E03")
.addTestDevice("E51508081F77DF84C129EE471DE67141")
.build();
adView.setVisibility(View.VISIBLE);
adView.loadAd(adRequest);
} else {
//if there's a problem, show error and close app
GooglePlayServicesUtil.getErrorDialog(adresult, MainActivity.this, 0, new DialogInterface.OnCancelListener() {
@Override
public void onCancel(DialogInterface dialogInterface) {
finish();
}
}).show();
}
}
在相应的活动方法中调用adView的pause()
、resume()
和destroy()
。实际上,这不会影响应用程序的表现,但我宁愿避免内存泄漏。如何避免该异常?
