Android6.0动态权限

拨打电话时候控制权限,

加入v4依赖

Android6.0动态权限

在build.gradle里面加入如下依赖 ,

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'

implementation 'com.android.support:support-v4:26.0.2'//我这里把27改成了26

// 在 GitHub 上搜索 PermissionsDispatcher 点击第一个 Java 目录下的文章导入依赖（ ${latest.version} 改为 3.0.1 ） compile('com.github.hotchemi:permissionsdispatcher:3.0.1') { // if you don't use android.app.Fragment you can exclude support for them exclude module: "support-v13" } annotationProcessor "com.github.hotchemi:permissionsdispatcher-processor:3.0.1" }
