我想为应用内购买实施Google-Analytics和Soomla商店。问题是,每次我想跟踪屏幕时,我的应用程序都会与Android崩溃。在iOS下,它就像一个魅力。
坠机原因:
java.lang.ClassCastException:com.soomla.SoomlaApp无法强制转换为org.cocos2dx.cpp.AnalyticsApplication
我认为AndroidManifest.xml中存在错误。我对Android很新,但我在iOS开发方面经验丰富。
当我在C ++代码中调用GoogleAnalyticsTracker::sendScreen("Test Screen")
时发生崩溃。
GoogleAnalyticsTracker.cpp的一部分:
void GoogleAnalyticsTracker::sendScreen(const char* screenName)
{
sendScreenJNI(screenName);
}
GoogleAnalyticsTracker_JNI.cpp的一部分
#include <jni.h>
#include "platform/android/jni/JniHelper.h"
#include "GoogleAnalyticsTracker_JNI.h"
#define CLASS_NAME "org/cocos2dx/cpp/AppActivity"
void sendScreenJNI(const char* screenName) {
cocos2d::JniMethodInfo t;
if (cocos2d::JniHelper::getStaticMethodInfo(t, CLASS_NAME, "sendScreen", "(Ljava/lang/String;)V"))
{
jstring jScreenName = t.env->NewStringUTF(screenName);
t.env->CallStaticVoidMethod(t.classID, t.methodID, jScreenName);
t.env->DeleteLocalRef(jScreenName);
t.env->DeleteLocalRef(t.classID);
}
}
我的AndroidManifest.xml的一部分:
<application android:name="com.soomla.SoomlaApp" android:label="@string/app_name"
android:icon="@drawable/icon">
<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/app_id"/>
<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />
<!-- Tell Cocos2dxActivity the name of our .so -->
<meta-data android:name="android.app.lib_name"
android:value="cocos2dcpp" />
<activity android:name="org.cocos2dx.cpp.AppActivity"
android:label="@string/app_name"
android:screenOrientation="landscape"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
android:configChanges="orientation">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="org.cocos2dx.cpp.AnalyticsApplication"/>
<activity android:name="com.soomla.store.billing.google.GooglePlayIabService$IabActivity"
android:theme="@android:style/Theme.Translucent.NoTitleBar.Fullscreen"/>
<meta-data android:name="billing.service" android:value="google.GooglePlayIabService"/>
</application>
这是“AnalyticsApplication.java的代码”
package org.cocos2dx.cpp;
import com.google.android.gms.analytics.GoogleAnalytics;
import com.google.android.gms.analytics.Tracker;
import ch.steeve.game.R;
import android.app.Application;
public class AnalyticsApplication extends Application {
Tracker mTracker;
synchronized Tracker getTracker() {
if (mTracker == null) {
GoogleAnalytics analytics = GoogleAnalytics.getInstance(this);
mTracker = analytics.newTracker(R.xml.ga_tracker);
}
return mTracker;
}
}
AppActivity.java的一部分
public static void sendScreen(String screenName) {
Tracker t = ((AnalyticsApplication) Cocos2dxActivity.getContext().getApplicationContext()).getTracker();
t.setScreenName(screenName);
t.send(new HitBuilders.AppViewBuilder().build());
}
答案 0 :(得分:1)
AndroidManifest中的此字符串不正确:
活动android:name =“org.cocos2dx.cpp.AnalyticsApplication”
AnalyticsApplication不是活动,它是应用程序。删除此字符串。
您的AnalyticsApplication应扩展com.soomla.SoomlaApp
在AndroidManifest中替换字符串:
应用程序android:name =“com.soomla.SoomlaApp”android:label =“@ string / app_name” 机器人:图标= “@绘制/图标”
到
应用程序android:name =“org.cocos2dx.cpp.AnalyticsApplication”android:label =“@ string / app_name” 机器人:图标= “@绘制/图标”
