Android 6.0调用相机图册崩溃的完美解决方案

概述最近客户更新系统发现，以前的项目在调用相机的时候，闪退掉了，很奇怪，后来查阅后发现，Android6.0以后需要程序授权相机权限，默认会给出提示，让用户授权，个人感觉这一特性很好，大概如下：

最近客户更新系统发现，以前的项目在调用相机的时候，闪退掉了，很奇怪，后来查阅后发现，AndroID 6.0以后需要程序授权相机权限，默认会给出提示，让用户授权，个人感觉这一特性很好，大概如下：

导入AndroID V4， V7包！

AndroID Studio 导入很简单，右键项目后找到dependency就ok了。

继承AppCompatActivity

public class MainActivity extends AppCompatActivity

引入需要的类库

import androID.support.design.Widget.Snackbar;import androID.support.v4.app.ActivityCompat;import androID.support.v7.app.AppCompatActivity;

检查相机权限，并请求权限

// BEGIN_INCLUDE(camera_permission_request)if (ActivityCompat.shouldShowRequestPermissionRationale(this,Manifest.permission.CAMERA)) {// ProvIDe an additional rationale to the user if the permission was not granted// and the user would benefit from additional context for the use of the permission.// For example if the user has prevIoUsly denIEd the permission.Log.i(TAG,"displaying camera permission rationale to provIDe additional context.");Snackbar.make(mLayout,R.string.permission_camera_rationale,Snackbar.LENGTH_INDEFINITE).setAction(R.string.ok,new VIEw.OnClickListener() {@OverrIDepublic voID onClick(VIEw vIEw) {ActivityCompat.requestPermissions(MainActivity.this,new String[]{Manifest.permission.CAMERA},REQUEST_CAMERA);}}).show();} else {// Camera permission has not been granted yet. Request it directly.ActivityCompat.requestPermissions(this,REQUEST_CAMERA);}// END_INCLUDE(camera_permission_request)

授权后接收回调方法：

/*** Callback received when a permissions request has been completed.*/@OverrIDepublic voID onRequestPermissionsResult(int requestCode,@NonNull String[] permissions,@NonNull int[] grantResults) {if (requestCode == REQUEST_CAMERA) {// BEGIN_INCLUDE(permission_result)// Received permission result for camera permission.Log.i(TAG,"Received response for Camera permission request.");// Check if the only required permission has been granted} }

混合应用开发解决方案

对于混合应用开发，有两种解决方案：

更改现有插件，添加权限访问代码（可能有有些麻烦）

调用权限插件：

安装：

cordova plugin add cordova-plugin-androID-permissions@0.10.0

包含的权限

// Example permissions.ACCESS_COARSE_LOCATIONpermissions.CAMERApermissions.GET_ACCOUNTSpermissions.READ_CONTACTSpermissions.READ_CALENDAR...

示例代码

var permissions = cordova.plugins.permissions;permissions.hasPermission(permissions.CAMERA,checkPermissionCallback,null);function checkPermissionCallback(status) {if(!status.hasPermission) {var errorCallback = function() {console.warn('Camera permission is not turned on');}permissions.requestPermission(permissions.CAMERA,function(status) {if(!status.hasPermission) errorCallback();},errorCallback);}}
