【问题描述】:
我将我的 Android Studio 更新到 2.3.2,之后 gradle 构建失败并出现以下错误:
error: incompatible types: Application cannot be converted to AnalyticsApplication.
我已尝试搜索它,但找不到任何相关内容。
build.gradle 文件:
android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "com.xxx.xxx"
minSdkVersion 15
targetSdkVersion 23
versionCode 17
versionName "1.6.7"
multiDexEnabled true
}
这里出错了,
// Obtain the shared Tracker instance.
AnalyticsApplication application = (AnalyticsApplication) getApplication();
mTracker = application.getDefaultTracker();
sharedPrefs = PreferenceManager
.getDefaultSharedPreferences(context);
sharedPrefsEditor = sharedPrefs.edit();
defineFields();
} catch (Exception e) {
e.printStackTrace();
}
AnalyticApplication.java:
import android.app.Application;
import android.support.multidex.MultiDexApplication;
import com.google.android.gms.analytics.GoogleAnalytics;
import com.google.android.gms.analytics.Tracker;
/**
* This is a subclass of {@link Application} used to provide shared objects for this app, such as the {@link Tracker}.*/
public class AnalyticsApplication extends MultiDexApplication {
private Tracker mTracker;
/**
* Gets the default {@link Tracker} for this {@link Application}.
* @return tracker
*/
synchronized public Tracker getDefaultTracker() {
if (mTracker == null) {
GoogleAnalytics analytics = GoogleAnalytics.getInstance(this);
// To enable debug logging use: adb shell setprop log.tag.GAv4 DEBUG
mTracker = analytics.newTracker(R.xml.global_tracker);
}
return mTracker;
}
}

使用 build、gradle 文件更新您的问题

还有你的应用程序类
