Question

构建失败并显示错误：unable to find symbol method checkSelfPermission 虽然我已经添加了支持库。它在构建之后会出错，但在Android Studio中没有用红色标记，或者标记为缺失，仍然在构建之后，会收到此方法丢失错误。

摇篮

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.3'
    }
}
apply plugin: 'com.android.application'


dependencies {
    compile fileTree(
            : '*.jar', dir: 'libs')
    compile project(':AndroidLicensingLibary')
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:support-v4:23.1.0'
    compile 'com.android.support:support-v13:23.0.+'

}

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }

        instrumentTest.setRoot('tests')
    }
}

主要活动（在setContent之后创建内部）

if (ContextCompat.checkSelfPermission(this,
                Manifest.permission.READ_CONTACTS)
                != PackageManager.PERMISSION_GRANTED) {

                ActivityCompat.requestPermissions(this,
                        new String[]{Manifest.permission.READ_CONTACTS},
                        1003);
        }
