Android 6.0多个权限申请，教你使用Google easypermissions框架，100%申请成功

    应用程序如果要申请多个权限，建议在程序的入口就把所有的权限申请好，省得后面一个一个去申请麻烦。一开始我直接使用搜索到的权限工具类，结果很不幸，程序挂了，有可能我申请的权限太多吧。废话不多说，阿凯教你一步一步把Android6.0权限申请下来：

注意事项：.普通权限不用申请，危险权限需要申请（危险权限申请一组中的一个默认获得整一组的权限），系统权限没法申请。（如果不知道哪些是普通权限，哪些是危险权限请对照这个链接http://blog.csdn.net/chenlinfeng772885775/article/details/53508204。）

1.在ManAndroidManifest.xml注册需要申请的权限;

<uses-permission android:name="android.permission.CALL_PHONE"/>

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

2.在build.gradle文件中引入google easypermission框架

dependencies {
    compile 'pub.devrel:easypermissions:0.4.2'
}

3.在程序入口的Activity实现EasyPermissions.PermissionCallbacks接口，搞定。

public class MainActivity extends AppCompatActivity implements EasyPermissions.PermissionCallbacks {

    private static final int num = 123;//用于验证获取的权

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        requireSomePermission();// 申请权限
    }

    @AfterPermissionGranted(num)
    private void requireSomePermission() {
        String[] perms = {	

	// 把你想要申请的权限放进这里就行，注意用逗号隔开

	    Manifest.permission.CALL_PHONE,
            Manifest.permission.ACCESS_FINE_LOCATION,
            Manifest.permission.ACCESS_NETWORK_STATE,
        };
        if (EasyPermissions.hasPermissions(this, perms)) {
            // Already have permission, do the thing
            // ...
            Toast.makeText(this, "Permissions Granted!", Toast.LENGTH_LONG).show();
        } else {
            // Do not have permissions, request them now
            EasyPermissions.requestPermissions(this, getString(R.string.rationale_phone),
                    num, perms);
        }
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);

        // EasyPermissions handles the request result.
        EasyPermissions.onRequestPermissionsResult(requestCode, permissions, grantResults, this);
    }


    @Override
    public void onPermissionsGranted(int requestCode, List perms) {
        //Toast.makeText(this, "Permissions Granted!", Toast.LENGTH_LONG).show();
    }

    @Override
    public void onPermissionsDenied(int requestCode, List perms) {
        //Toast.makeText(this, "Permissions Denied!", Toast.LENGTH_LONG).show();
    }
}
