我不知道确切的错误发生在哪里，但是我的猜测是当我尝试在此处尝试将位图压缩为WEBP格式时：
public String saveImage(String id, Bitmap bitmap) {
if(bitmap != null) {
File folder = new File(getFilesDir() + "/packs", id);
if (!folder.exists())
folder.mkdirs();
String stickerName = "sticker" + String.valueOf(TimeUnit.MILLISECONDS.toSeconds(System.currentTimeMillis())) + ".webp";
File filename = new File(folder, stickerName);
try {
if (!filename.exists())
filename.createNewFile();
FileOutputStream out = new FileOutputStream(filename);
bitmap.compress(Bitmap.CompressFormat.WEBP, 100, out);
out.close();
} catch (Exception e) {
e.printStackTrace();
}
return stickerName;
} else {
return null;
}
}
位图是在我的自定义视图中创建的，然后保存为WEBP，但是每次尝试都会给我一个错误。正如我说的，我不知道如何调试此错误消息，所以如果我完全错了，请说。
提前致谢！
最佳答案
所以我最终使用了libwebp而不是Bitmap.compress(Bitmap.CompressFormat.WEBP, 100, out);，它现在可以正常工作了。这是有关如何使用libwebp http://masashi-k.blogspot.com/2014/02/webp-in-android.html的教程。
