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:
/** * callback received when a permissions request has been completed. */ @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); } }
以上所述是小编给大家介绍的android 6.0调用相机图册崩溃的完美解决方案,希望对大家有所帮助
