博客提供了Android动态权限申请的代码，包含单个和多个权限申请的方法。当系统版本大于等于Android M时，会检查权限是否已授予，未授予则进行权限申请，并处理权限申请成功或失败的回调。还给出了代码封装的下载链接。
/**
* 动态权限申请(单个)
* @param activity
* @param requestCodeOut 申请码
* @param permissionPrepare2Request 申请的权限
* @return
*/
public boolean requestPermission(Activity activity, final int requestCodeOut, String permissionPrepare2Request){
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M){
int permissionCheck = ContextCompat.checkSelfPermission(activity, permissionPrepare2Request);
if (permissionCheck == PackageManager.PERMISSION_GRANTED) {
return true;
} else {
registTempOnPermissionRequestCallBack(new OnPermissionRequestCallBack() {
@Override
public void onGrantedSuccess(int requestCode) {
if(requestCodeOut == requestCode){
if(onPermissionRequestCallBack != null){
onPermissionRequestCallBack.onGrantedSuccess(requestCode);
}
}
}
@Override
public void onGrantedFailure(int requestCode) {
if(requestCodeOut == requestCode){
if(onPermissionRequestCallBack != null){
onPermissionRequestCallBack.onGrantedFailure(requestCode);

}
}
});
String[] deniedPermissions = new String[]{permissionPrepare2Request};
ActivityCompat.requestPermissions(activity, deniedPermissions, requestCodeOut);
return false;
}
}else{
return true;
}

/**
