Android代码动态申请sdcard读写权限

import android.app.Activity;
import android.content.pm.PackageManager;
import android.support.v4.app.ActivityCompat;

public class CheckStoragePermission {

    private static final int REQUEST_EXTERNAL_STORAGE = 1;
    private static final String[] PERMISSIONS_STORAGE = {
        "android.permission.READ_EXTERNAL_STORAGE",
        "android.permission.WRITE_EXTERNAL_STORAGE" };


    public static void verifyStoragePermissions(Activity activity) {

        try {
            //检测是否有写的权限
            int permission = ActivityCompat.checkSelfPermission(activity,PERMISSIONS_STORAGE[1]);
            if (permission != PackageManager.PERMISSION_GRANTED) {
                // 没有写的权限，去申请写的权限，会弹出对话框
                ActivityCompat.requestPermissions(activity, PERMISSIONS_STORAGE,REQUEST_EXTERNAL_STORAGE);
            }
        } catch (Exception e) {}
    }
