Question

当我通过Picasso将图像的ArrayList加载到平板电脑（Nexus7）中的GridView时，

Picasso.with(getActivity()).load(movie.getMovieImageUrl()).into(imageViewPosterImage);

我的应用程序因以下错误而崩溃。但是，我的应用程序在我的手机（LG G2）上运行良好。

我严重怀疑它是由于加载图像的消耗而引起的。虽然通过jar Picasso加载，但平板电脑中的图像比手机大得多。
我该如何修复这个错误？

事实证明这不是加载问题，而是从SQLiteDatabase获取数据的问题。

public ArrayList<MovieInfoModel> getAllMovieInfo() {
    Log.v(LOG_TAG, "getAllMovieInfo() executed.");
    SQLiteDatabase db = this.getReadableDatabase();
    ArrayList<MovieInfoModel> allMovieInfoArrayList = new ArrayList<>();

    String getAllMovieInfoQuery = "SELECT * FROM " + STORED_TABLE_NAME;
    Cursor cursor = db.rawQuery(getAllMovieInfoQuery, null);
    cursor.moveToFirst();
    while (!cursor.isAfterLast()) {
        Gson gson = new Gson();
        MovieInfoModel movieInfo = new MovieInfoModel();
        movieInfo.setMovieId(cursor.getLong(cursor.getColumnIndex(MOVIE_ID)));
        movieInfo.setMovieOriginalTitle(cursor.getString(cursor.getColumnIndex(MOVIE_ORIGINAL_TITLE)));
        movieInfo.setMoviePlotSynopsis(cursor.getString(cursor.getColumnIndex(MOVIE_PLOT_SYNOPSIS)));
        movieInfo.setMovieUserRating(cursor.getString(cursor.getColumnIndex(MOVIE_USER_RATING)));
        movieInfo.setMovieReleaseDate(cursor.getString(cursor.getColumnIndex(MOVIE_RELEASE_DATE)));
        ArrayList<String> movieTrailerUrlArrayList = gson.fromJson(cursor.getString(cursor.getColumnIndex(MOVIE_TRAILER_URL_JSON_STRING)), new TypeToken<ArrayList<String>>() {
        }.getType());
        movieInfo.setMovieTrailerUrlArrayList(movieTrailerUrlArrayList);
        ArrayList<MovieReviewModel> movieReviewArrayList = gson.fromJson(cursor.getString(cursor.getColumnIndex(MOVIE_REVIEW_JSON_STRING)), new TypeToken<ArrayList<MovieReviewModel>>() {
        }.getType());

        movieInfo.setMovieReviewArrayList(movieReviewArrayList);
        allMovieInfoArrayList.add(movieInfo);
    }
    return allMovieInfoArrayList;
}

错误行是

ArrayList<MovieReviewModel> movieReviewArrayList = gson.fromJson(cursor.getString(cursor.getColumnIndex(MOVIE_REVIEW_JSON_STRING)), new TypeToken<ArrayList<MovieReviewModel>>() {
        }.getType());

可能由movieReviewArrayList造成的太大。 movieReviewArrayList是MovieReviewModel（一个自定义对象）的ArrayList，以前存储为GSON.jar转换的JSON字符串，稍后需要时转为ArrayList<MovieInfoModel>（通过GSON.jar）。应该如何存储这么大的文件？
如果有人需要，我会发布我的MovieReviewModel课程：

public class MovieReviewModel implements Parcelable {

private String reviewAuthor;
private String reviewContent;
private String reviewUrl;

constructors
setters
getters
Parcelable implementations
}

Answer 1

对我来说有同样的问题

.memoryPolicy(MemoryPolicy.NO_STORE)

工作，例如

    Picasso.with(getActivity()).load(backdropURL).memoryPolicy(MemoryPolicy.NO_STORE).centerCrop().fit().into(backdropView);

通过Picasso加载图像时的java.lang.OutOfMemoryError
