Android(安卓)6.0 权限管理工具类

简单使用例子
implements EasyPermission.PermissionCallback
然后在onRequestPermissionsResult里面调下面的方法
@Overridepublic void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { EasyPermission.onRequestPermissionsResult(this, requestCode, permissions, grantResults);} onPermissionGranted 用户授予所有权限
onPermissionDenied 用户拒绝至少一个权限
申请权限
EasyPermission.with(this) .addRequestCode(RC_CAMERA_AND_AUDIO) .permissions(new String[]{Manifest.permission.RECORD_AUDIO, Manifest.permission.CAMERA}) .rationale(getString(R.string.rationale_camera_audio)) .request();更多相关文章
