Android 6.0调用相机图册崩溃的完美解决方案

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() {
@Override
public 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, new String[]{Manifest.permission.CAMERA},
REQUEST_CAMERA);
}
// END_INCLUDE(camera_permission_request)

授权后接收回调方法：

@Override
public 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_LOCATION
permissions.CAMERA
permissions.GET_ACCOUNTS
permissions.READ_CONTACTS
permissions.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);
}
}
