android.os.FileUriExposedException

在华为拍照启动时报的异常  下面时bugly提供的解决方法 但是我自己在别的页面也是用拍照 没有问题 所以改成了自己的方法

解决方案

因为buildsdk是>=24,所以调用Uri.fromFile时保错，解决方法：在application的onCreate里:StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();StrictMode.setVmPolicy(builder.build());builder.detectFileUriExposure()SDK>24 和<24的解决方案public static void openFile(Context context, File file) {        Intent intent = new Intent();        intent.setAction(android.content.Intent.ACTION_VIEW);        Uri uri;        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {            intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);            Uri contentUri = FileProvider.getUriForFile(context,                    context.getApplicationContext().getPackageName() + ".provider",                    file);            intent.setDataAndType(contentUri, "application/vnd.android.package-archive");        } else {            uri = Uri.fromFile(file);            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);            intent.setDataAndType(uri, "application/vnd.android.package-archive");        }        context.startActivity(intent);    }<------------------------------分割线----------------------------->********************************************************************************为Android N调用相机时崩溃提供一种解决方法，亲测有效******其中 savePath 为临时保存的路径，tempFileName为拍照 ******后存储的照片名称。                                                           ***************************************************************By JayGoo ********************************************************************************** /**     * 从拍照获取图片     */    public void camera() {        Intent intent = null;        // 判断存储卡是否可以用，可用进行存储        if (StorageUtils.hasSdcard()) {            //设定拍照存放到自己指定的目录,可以先建好            File file = new File(savePath);            if(!file.exists()){                file.mkdirs();            }            Uri pictureUri;            File pictureFile = new File(savePath, tempFileName);            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {                intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);                ContentValues contentValues = new ContentValues(1);                contentValues.put(MediaStore.Images.Media.DATA, pictureFile.getAbsolutePath());                pictureUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,contentValues);            }else {                intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);                pictureUri = Uri.fromFile(pictureFile);            }            if (intent != null) {                intent.putExtra(MediaStore.EXTRA_OUTPUT,                        pictureUri);                startActivityForResult(intent, 1);            }        }    }<------------------------------分割线----------------------------->在Android N 安装apk文件时,也会报此错误,解决办法如下:http://www.jianshu.com/p/577816c3ce93  (By Trojx)

之前使用的方法 

这是修改前的代码

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);        intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);        String currentPhotoName = System.currentTimeMillis() + ".jpg";        File dir = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/zpay/");        File out = new File(dir, currentPhotoName);        PreferencesUtils.getInstance(this).put("REQUEST_PHOTO", out.getAbsolutePath());        Uri uri = Uri.fromFile(out);// 这个方法在华为中报了异常        intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);//        intent.putExtra(MediaStore.Images.Media.ORIENTATION, 180);        startActivityForResult(intent, REQUEST_PHOTO);

后修改为 

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);//        intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);        SimpleDateFormat timeStampFormat = new SimpleDateFormat("yyyyMMddHHmmss");        String filename = timeStampFormat.format(new Date());        ContentValues values = new ContentValues();        values.put(MediaStore.Images.Media.TITLE, filename);        Uri uri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);        intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);        PreferencesUtils.getInstance(this).put("REQUEST_PHOTO", NewBinderActivity.getPath(FeedbackActivity.this, uri));
