java - Android 相机未打开以捕获图像

Question

这是相机 Intent

 if(f[which].equals("Camera")) {
                    try {
                        String imageFileName="outputImage_" + System.currentTimeMillis()+".png";
                        File outputImageFile=new File(pictureSaveFolderPath,imageFileName);
                        if(outputImageFile.exists()){
                            outputImageFile.delete();
                        }
                        outputImageFile.createNewFile();
                        imageUri=getImageUriByOsVersion(outputImageFile);
                        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                        intent.putExtra(MediaStore.EXTRA_OUTPUT,imageUri);
                        startActivityForResult(intent, 1);
                    } catch (Exception ex) {
                        ex.printStackTrace();
                    }
                }

Activity 结果

 if (requestCode == 1) {
                Uri selectedImage=imageUri;
                getApplicationContext().getContentResolver().notifyChange(selectedImage,null);
                ContentResolver cr=getApplicationContext().getContentResolver();
                try {
                    thumbnail = MediaStore.Images.Media.getBitmap(
                            cr, selectedImage);
                    imageView.setImageBitmap(thumbnail);
                    common.setBitmap(thumbnail);

                }catch (Exception e){
                    e.printStackTrace();
                }

                Uri tempUri = getImageUri(getApplicationContext(), thumbnail);
                File finalFile = new File(getRealPathFromURI(tempUri));
            } 

运行时权限

 private  boolean checkAndRequestPermissions() {
        int camera = ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA);
        int writePermission = ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE);
        int readPermission = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE);
        List<String> listPermissionsNeeded = new ArrayList<String>();
        if (camera != PackageManager.PERMISSION_GRANTED) {
            listPermissionsNeeded.add(Manifest.permission.CAMERA);
        }
        if (writePermission != PackageManager.PERMISSION_GRANTED){
            listPermissionsNeeded.add(Manifest.permission.WRITE_EXTERNAL_STORAGE);
        }if (readPermission != PackageManager.PERMISSION_GRANTED){
            listPermissionsNeeded.add(Manifest.permission.READ_EXTERNAL_STORAGE);
        }
        if (!listPermissionsNeeded.isEmpty()) {
            ActivityCompat.requestPermissions(this, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]),REQUEST_ID_MULTIPLE_PERMISSIONS);
            return false;
        }
        return true;
    }


    @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
    @Override
    public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
        switch (requestCode) {
            case REQUEST_ID_MULTIPLE_PERMISSIONS: {
                Map<String, Integer> perms = new HashMap<>();
                perms.put(Manifest.permission.CAMERA, PackageManager.PERMISSION_GRANTED);
                perms.put(Manifest.permission.READ_EXTERNAL_STORAGE,PackageManager.PERMISSION_GRANTED);
                perms.put(Manifest.permission.WRITE_EXTERNAL_STORAGE,PackageManager.PERMISSION_GRANTED);
                if (grantResults.length > 0) {
                    for (int i = 0; i < permissions.length; i++)
                        perms.put(permissions[i], grantResults[i]);
                    if (perms.get(Manifest.permission.CAMERA) == PackageManager.PERMISSION_GRANTED && perms.get(Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED && perms.get(Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {

                    } else {
                        if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.CAMERA) || ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) || ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.READ_EXTERNAL_STORAGE)) {
                            showDialogOK("Sorry, Camera and Storage Permission required for this activity. So please ensure the Camera and Storage permissions are enabled in settings",
                                    new DialogInterface.OnClickListener() {
                                        public void onClick(DialogInterface dialog, int which) {
                                            switch (which) {

                                    });
                        }
                    } }
            } }

我正在实现相机、图库和文件管理器 Intent ，该代码几天前就已工作，我不知道发生了什么，它现在无法工作。图库和文件管理器按照我的预期完美工作，但相机 Intent 根本不工作工作。

注意:java.lang.SecurityException:UID 10363没有权限

当我选择相机选项时出现上述错误

您基本上可以在运行时使用请求权限，我也没有像您的风格那样获得权限，但我可以像下面的代码一样在运行时获得权限:

ActivityCompat.requestPermissions(this,
                        new String[]{Manifest.permission.[YourPermission]},
                        1);


@Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        switch (requestCode) {

            case 1:
                if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    // do something
                } else {
                    // do something
                }
                break;
}
