問(wèn)題描述

之前沒(méi)問(wèn)題的項(xiàng)目打開之后Gradle報(bào)錯(cuò)：

Try Again以后還是不行，Messages顯示如下：

仔細(xì)檢查沒(méi)有發(fā)現(xiàn)問(wèn)題，最后新建一個(gè)工程把文件挨個(gè)拷貝，新工程一切正常，想知道遇到這種問(wèn)題如何解決，不能總是新建工程吧。最后附上還是有問(wèn)題的老工程AndroidManifest文件：

<?xml version='1.0' encoding='utf-8' standalone='no'?><manifest xmlns:android='http://schemas.android.com/apk/res/android' android:installLocation='preferExternal' package='com.kunpo.loner'> <supports-screens android:anyDensity='true' android:largeScreens='true' android:normalScreens='true' android:smallScreens='true' android:xlargeScreens='true'/> <uses-sdk android:minSdkVersion='15' android:targetSdkVersion='25'/> <uses-permission android:name='android.permission.INTERNET' /> <uses-permission android:name='android.permission.ACCESS_NETWORK_STATE' /> <uses-permission android:name='android.permission.ACCESS_WIFI_STATE' /> <uses-permission android:name='android.permission.READ_PHONE_STATE' /> <uses-permission android:name='android.permission.MODIFY_AUDIO_SETTINGS'/> <uses-permission android:name='android.permission.WRITE_EXTERNAL_STORAGE' /> <application android:icon='@drawable/icon' android:isGame='false' android:label='@string/app_name'><activity android:configChanges='locale|fontScale|keyboard|keyboardHidden|mcc|mnc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|touchscreen|uiMode' android:label='@string/app_name' android:launchMode='singleTask' android:name='com.kunpo.loner.MainActivity' android:screenOrientation='landscape'> <intent-filter><action android:name='android.intent.action.MAIN'/><category android:name='android.intent.category.LAUNCHER'/> </intent-filter> <intent-filter><action android:name='android.intent.action.VIEW'/><category android:name='android.intent.category.DEFAULT'/><data android:scheme='wxf111111111111'/> </intent-filter> <meta-data android:name='unityplayer.UnityActivity' android:value='true'/></activity><activity android:name='com.kunpo.loner.wxapi.WXPayEntryActivity' android:exported='true' android:launchMode='singleTop' /><activity android:name='com.alipay.sdk.app.H5PayActivity' android:configChanges='orientation|keyboardHidden|navigation' android:exported='false' android:screenOrientation='behind' ></activity><activity android:name='com.alipay.sdk.auth.AuthActivity' android:configChanges='orientation|keyboardHidden|navigation' android:exported='false' android:screenOrientation='behind' ></activity> </application> <uses-feature android:name='android.hardware.touchscreen' android:required='false'/> <uses-feature android:name='android.hardware.touchscreen.multitouch' android:required='false'/> <uses-feature android:name='android.hardware.touchscreen.multitouch.distinct' android:required='false'/></manifest>

代碼排版好像有點(diǎn)問(wèn)題，請(qǐng)見諒。

問(wèn)題解答

你看看你的gradle里面有 applicationId 嗎？ 如果沒(méi)有的話加上應(yīng)該就可以了
