Question

大家好，我在Android Studio中遇到一个奇怪的问题，同时运行一个全新的导航抽屉项目。应用程序在启动MainActivity时出现错误

04-21 17:23:30.588 15257-15257/brsnc.infotech.dos.com.test E/AndroidRuntime: FATAL EXCEPTION: main

奇怪的是它只发生在导航抽屉活动中。我尝试过其他活动，但他们工作正常。

这是我的build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"
    defaultConfig {
        applicationId "brsnc.infotech.dos.com.test"
        minSdkVersion 15
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.1.1'
    compile 'com.android.support:design:25.1.1'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    testCompile 'junit:junit:4.12'
}

更新这是我的布局文件。

Answer 1

可能是您的SDK tools不是updated。转到Android SDK Manager并更新以下内容：

Android SDK工具
Android SDK构建工具
Android SDK平台工具
Android支持存储库

最后，Clean和Rebuild您的项目再次Run。

希望这能解决问题。
