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, new String[]{Manifest.permission.CAMERA},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);}}
