安卓系统6.0以上需要动态申请手机权限，下面直接贴上申请的代码模版

private void requestPermission(String[]permissions,int code,PermissionCallback callback){        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {            if (checkPermissions(permissions)) {                ActivityCompat.requestPermissions(this, permissions, code);                mPermissionCallbacks.put(code, callback);            }else { //6.0以上已经动态申请了权限                callback.onSuccess();            }        }else {//6.0一下，无需动态申请            callback.onSuccess();        }    }    private boolean checkPermissions(String[] permossions){        BaseActivity activity = MyEnvironment.activity();        for(String permission:permossions){            if(ActivityCompat.checkSelfPermission(activity, permission) == PackageManager.PERMISSION_GRANTED){                return false;            }        }        return true;    }    @Override    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {        super.onRequestPermissionsResult(requestCode, permissions, grantResults);        PermissionCallback callback = mPermissionCallbacks.get(requestCode);        int success = 0;        for (int grantResult : grantResults) {            success += grantResult == PackageManager.PERMISSION_GRANTED ? 1 : 0;        }        if (success == grantResults.length) {            callback.onSuccess();//申请成功        } else {            callback.onError(new Exception("申请权限失败"));        }        mPermissionCallbacks.remove(requestCode);    }    protected SparseArray
    
      mPermissionCallbacks = new SparseArray
     
      ();    public interface PermissionCallback {        void onSuccess();        void onError(Exception exception);    }
     
    

以上方法一般放在基类，需要动态申请其他权限的时候，只需要添加对应的code和权限permission就可以了，添加的方式如下

public static final int REQUEST_CODE_CAMERA = 3;    public static final int REQUEST_CODE_EXTERNAL_STORAGE = 4;    public void requestExternalPermission(PermissionCallback callback){        requestPermission(new String[]{Manifest.permission.READ_EXTERNAL_STORAGE,Manifest.permission.WRITE_EXTERNAL_STORAGE},REQUEST_CODE_EXTERNAL_STORAGE,callback);    }    public void requestCameraPermission(PermissionCallback callback){        requestPermission(new String[]{Manifest.permission.CAMERA},REQUEST_CODE_CAMERA,callback);    }

自己定义好code就可以了，对外只需要暴露requestXXXPermission方法，真正申请权限的代码在requestPermission方法中，已经整理成模版，每个权限对应的code应当是不相同的。

调用：

activity.requestCameraPermission(new PermissionCallback() {            @Override            public void onSuccess() {//动态申请成功                takePhote();            }            @Override            public void onError(Exception exception) {                Toast.makeText(PermissionActivity.this, "请通过设置允许应用获取权限", Toast.LENGTH_SHORT).show();            }        });

只需要提供一个回调就可以了，是不是很简单易用
