我正在关注这里的教程。
我已经完成了所有步骤，当我在 eclipse 中单击运行时，它似乎可以在应用程序进入我的手机时工作。
但是，当我单击它时，会出现“强制关闭错误”。
当我从电脑上拔下手机时，我可以拍照，但是当我对它进行 ocr 操作时，我得到了强制关闭错误。
我正在使用 Windows 7，阅读它应该工作的页面上的评论
这是我得到的一些 logcat 错误的打印 -
@Override
public void onCreate(Bundle savedInstanceState) {
String[] paths = new String[] { DATA_PATH, DATA_PATH + "tessdata/" };
for (String path : paths) {
File dir = new File(path);
if (!dir.exists()) {
if (!dir.mkdirs()) {
Log.v(TAG, "ERROR: Creation of directory " + path + " on sdcard failed");
return;
} else {
Log.v(TAG, "Created directory " + path + " on sdcard");
}
}
}
// lang.traineddata file with the app (in assets folder)
// You can get them at:
// http://code.google.com/p/tesseract-ocr/downloads/list
// This area needs work and optimization
if (!(new File(DATA_PATH + "tessdata/" + lang + ".traineddata")).exists()) {
try {
AssetManager assetManager = getAssets();
InputStream in = assetManager.open("tessdata/eng.traineddata");
//GZIPInputStream gin = new GZIPInputStream(in);
OutputStream out = new FileOutputStream(DATA_PATH

// Transfer bytes from in to out

//while ((lenf = gin.read(buff)) > 0) {

}
in.close();
//gin.close();
out.close();
