Android 6.0 动态权限参考 https://blog.csdn.net/qq_27400335/article/details/79412774Android 7.0 文件写入问题在AndroidManifest.xml 配置 FileProvider为了防止重复 android:authorities 一般配置为 包名.fileProvider //调用册并裁减 //fileName 为全局变量(这里为了直观就没有写) String fileName = CameraUtils.photoAlbum(activity);----------------------------------------------------------//调用拍照并裁剪 String fileName = CameraUtils.photograph(activity);
------------------------------------------------------------------------------------
//调用拍视频
fileName = CameraUtils.shootVideo(activity);--------------------------------------------------------------------------------------
//调用录音
CameraUtils.startRecord(new CameraUtils.RecordingCallBack() { @Override public void name(String name) { fileName = name; } @Override public void intent(Intent intent) { startActivityForResult(intent, CameraUtils.RECORD_FLAG); }});--------------------------------------------------------------------------------------------
