Android无法解析符号OnRequestPermissionsResultCallback

问题描述

限时删除！！

我是android新手，我正在尝试构建一个应用程序来显示我的当前位置，并且我正在关注来自google链接的apidemos中的设置。这是一项任务的一部分，所以我不想透露我的最终目标是什么。现在我想能够在我的应用上使用gps位置。我将发布我的活动代码，xml布局代码，清单代码和gradle代码。如果还有其他东西需要发布，请告诉我。我尝试过搜索，但找不到任何东西。如果它有帮助，我主要是为我的手机做这个。 Nexus 6p Android 6.0.1编辑：得到OnRequestPermissionsResultCallback工作，但仍然有PermissionUtils给我一个错误。

我会评论我的错误/无法解决的地方。

这里是我更新后的build gradle
apply plugin：'com.android.application'

  android {

 buildToolsVersion23.0.2
 
 defaultConfig {
 applicationIdcom.example.name.app
 minSdkVersion 15 
 targetSdkVersion 23 
 versionCode 1 
 versionName1.0
} 
 buildTypes {
 release {
 minifyEnabled false 
 proguardFiles getDefaultProguardFile（'proguard-android.txt'），'proguard-rules.pro'
} 
} 
 
 
编译fileTree（include：['* .jar']，dir：'libs'）
 compile'c​​om.android.support:appcompat- v7：23.2.0'
 compile'c​​om.google.android.gms：play-services：8.4.0'
 compile'c​​om.android.support:support-v13:23.2.0'
} 
  

决议案

升级：

• compileSdkVersion 至 23


• buildToolsVersion 至 23.0.2 com.android.support:appcompat-v7 和 com.android.support： support-v13 至 23.2.0

您缺少的符号来自 appcompat-v7 的23.xy版本;其他变化是保持主要版本同步。

另外，请注意 7.5.0 是一个宁可旧版的 play-services ;我建议将它升级到 8.4.0 。

而且，请记住，您的所有运行时权限是毫无意义的，给定 targetSdkVersion 22 。

I am new to android and I am trying to build an app to show my current location and I am following the setup in apidemos from google linked here. This is part of an assignment so I do not want to disclose what my ultimate goal is. For now I want to be able to have gps location working on my app. I will post my activity code, xml layout code, manifest code and gradle code. If there is anything else I need to post please let me know. I have tried searching but I couldn't find anything. Also if it helps I am mainly making this for my phone. Nexus 6p Android 6.0.1

EDIT:Got OnRequestPermissionsResultCallback Working but still have PermissionUtils giving me an error.

I will comment where my errors/cannot resolves are occurring

            android:name="com.google.android.gms.version"
            android:value="@integer/google_play_services_version" />
        <activity
            android:name=".MapsActivity"
            android:label="@string/title_activity_maps"
            android:screenOrientation="portrait">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

    </manifest>

And here is my updated build gradle apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.example.name.app"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:23.2.0'
    compile 'com.google.android.gms:play-services:8.4.0'
    compile 'com.android.support:support-v13:23.2.0'
}

解决方案

Upgrade:

• compileSdkVersion to 23
• buildToolsVersion to 23.0.2
• com.android.support:appcompat-v7 and com.android.support:support-v13 to 23.2.0

Your missing symbol is from a 23.x.y edition of appcompat-v7; the other changes are to keep the major version in sync.

Also, note that 7.5.0 is a rather old edition of play-services; I recommend upgrading that to 8.4.0.

And, bear in mind that all your runtime permission stuff is pointless, given targetSdkVersion 22.
