AOSP键盘：的NoSuchMethodError - createEmptyDictFileNative [英] AOSP Keyboard: NoSuchMethodError - createEmptyDictFileNative

问题描述

我想加一些定制code，以获得关键的触摸pressure值之后建立从5.0.2分支AOSP键盘。我使用午餐全英来构建源，并使用毫米打造LatinIME我已经添加了我的后变化。

I'm trying to build the AOSP keyboard from the 5.0.2 branch after adding some custom code to obtain pressure values for key touches. I'm using lunch full-eng to build the source and using mm to build LatinIME after I've added my changes.

我在和pre-优化麻烦，但在这里帮助就如何解决<一个href=\"http://stackoverflow.com/questions/28005500/custom-aosp-keyboard-error-dictionaryprovider-classnotfoundexception\">that.现在我有以下错误：

I was having trouble with pre-optimization but was helped here on how to solve that. I'm now having the following error:

LatinIME.java 有以下有关此调用的评论：

LatinIME.java has the following comment regarding this call:

加载本地库急切地避免意外
  的UnsatisfiedLinkError在初始
  JNI调用尽可能多的。

Loading the native library eagerly to avoid unexpected UnsatisfiedLinkError at the initial JNI call as much as possible.

和 JniUtils.java 进行呼叫

的System.loadLibrary（JniLibName.JNI_LIB_NAME）;

其中， JNI_LIB_NAME 在 com.android.inputmethod.latin.define.JniLibName 假想定义。这是我相信我的问题是部分

where JNI_LIB_NAME is supposedly defined in com.android.inputmethod.latin.define.JniLibName. This is where I believe my issue partially is.

1. BinaryDictionary.java 不包含 createEmptyDictFileNave 法


2. com.android.inputmethod.latin.define.JniLibName 源$ C ​​$ C，我从谷歌的回购得到了根本不存在。

1. BinaryDictionary.java does not contain a createEmptyDictFileNave method
2. com.android.inputmethod.latin.define.JniLibName does not exist in the source code I got from Google's repo.

像往常一样，任何帮助将大大pciated因为我很新的Andr​​oid源建筑AP $ P $。谢谢你。

Like always, any help would be greatly appreciated as I'm very new to Android source building. Thank you.

问候，

推荐答案

createEmptyDictFileNative在<一个href=\"http://androidxref.com/5.0.0_r2/xref/packages/inputmethods/LatinIME/java/src/com/android/inputmethod/latin/utils/BinaryDictionaryUtils.java#43\"相对=nofollow> BinaryDictionaryUtils 并JNI_LIB_NAME是<一个href=\"http://androidxref.com/5.0.0_r2/xref/packages/inputmethods/LatinIME/java-overridable/src/com/android/inputmethod/latin/define/JniLibName.java#24\"相对=nofollow>这里。

createEmptyDictFileNative is in BinaryDictionaryUtils and JNI_LIB_NAME is here.

您可能有libjni_latinime.so过时的版本不包含的 createEmptyDictFileNative 的功能导出JNI。

You might have an outdated version of libjni_latinime.so that does not contain the createEmptyDictFileNative function exported for JNI.

拉​​库，并验证该方法存在：

Pull the library and verify that method exists:

adb pull /system/lib/libjni_latinime.so
nm -D libjni_latinime.so | grep createEmptyDictFile

如果库中不存在，则需要重新安装/系统并进行安装。如果本地方法不存在，则需要更新libjni_latinime.so共享库

If the library doesn't exist, you need to remount /system and install it. If the native method doesn't exist, you need an updated libjni_latinime.so shared library
