Android对6.0及以上的版本做了更强的权限控制。如打电话这种需要动态申请。我推荐使用github上start最多的PermissionsDispatcher作为权限管理。
说明：
一,使用的Androidstudio版本为3.2.1
二,使用的permissionsdispatcher版本为3.1.0
github地址为：https://github.com/permissions-dispatcher/PermissionsDispatcher
展示效果:

现在正式开始
1，在build.gradle中做如下代码1--4步骤所示配置。
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.mumu.jspermissions"
minSdkVersion 15
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
//1，增加jitpack支持
allprojects {
repositories {
maven { url "https://jitpack.io" }
maven { url "https://maven.google.com" }
flatDir {
dirs 'libs'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
//2，butterKnife
implementation 'com.jakewharton:butterknife:8.8.1'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'
//3，自己封装的弹窗
implementation 'com.github.mamumu:MMAlertDialog:10'
//4，permissionsdispatcher权限
implementation'com.github.hotchemi:permissionsdispatcher:3.1.0'
annotationProcessor 'com.github.hotchemi:permissionsdispatcher-processor:3.1.0'
}
2，在AndroidManifest.xml中添加对应的权限，我demo中只是用拨打电话的权限，如果需要其他权限，都要先在这添加上。
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.mumu.jspermissions">
//拨打电话的权限
<uses-permission android:name="android.permission.CALL_PHONE" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
3，前面1和2步骤完成了基本配置，核心6步来了。详情看下图和代码中注释。注意，被权限注解的方法不能用private修饰。

@NeedsPermission(Manifest.permission.CALL_PHONE)
void callPhone() {

@OnPermissionDenied(Manifest.permission.CALL_PHONE)
void showDenied() {
Toast.makeText(MainActivity.this, "无法获得权限", Toast.LENGTH_SHORT).show();
}
/**

@OnNeverAskAgain(Manifest.permission.CALL_PHONE)
void showNeverAskAgain() {
MMAlertDialogUtils.showDialog(MainActivity.this,

@Override

//引导用户至设置页手动授权
Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
Uri uri = Uri.fromParts("package", MainActivity.this.getPackageName(), null);
intent.setData(uri);
startActivity(intent);
dialog.dismiss();
}
});
}
/**

*/
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
MainActivityPermissionsDispatcher.onRequestPermissionsResult(MainActivity.this, requestCode, grantResults);
}
}
4，MainActivityPermissionsDispatcher类需要如下图操作才可以对应生成，规则是当前类名+PermissionsDispatcher。

5，对应github地址
