立ち往生しています。カメラから写真を取得して保存する私の方法は次のとおりです。

> > @Override
>     public File createImageFile() throws IOException {
>         String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
>         String imageFileName = "JPEG_" + timeStamp + "_";
>         File storageDir = context.getExternalFilesDir(Environment.DIRECTORY_PICTURES);
>         File imageFile = File.createTempFile(imageFileName, ".jpg", storageDir);
>         model.currentPhotoPath = imageFile.getAbsolutePath();
>         return imageFile;
>     }

@Override
public Intent getCameraPictureIntent(PackageManager packageManager) {
    Intent pictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    if (pictureIntent.resolveActivity(packageManager) != null) {
        try {
            model.userPicFile = createImageFile();
        } catch (IOException e) {
            Log.i(TAG, "Can't create file!");
        }
        if (model.userPicFile != null) {
            model.userPicFileUri = FileProvider.getUriForFile(context,
                    "com.internship.droidz.talkin.fileprovider",
                    model.userPicFile);
            pictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, model.userPicFileUri);
        }
    }
    return pictureIntent;
}

tempfile を作成してから、uri を取得し、intent に設定します。そして、結果のstartActivity。写真を撮って送信すると、アプリがクラッシュします。Logcat は何も言いません。

ここに保存されたファイルとURIがあります：

    public class RegistrationModel implements RegistrationContract.RegistrationModel {

    String currentPhotoPath;
    Uri userPicFileUri;
    File userPicFile;
}

Manifest.xml のアクセス許可は次のとおりです。

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

<uses-feature android:name="android.hardware.camera"
    android:required="false" />

API 19+ 向けのコンパイル

それは Log.i の言うことです:

ありがとうございます！answer Android - file provider - Permission Denialを使用して、この問題を解決しました

    List<ResolveInfo> resInfoList = context.getPackageManager().queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
for (ResolveInfo resolveInfo : resInfoList) {
    String packageName = resolveInfo.activityInfo.packageName;
    context.grantUriPermission(packageName, uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
}
