GooglTTS中文包预置_flyfly程序媛-CSDN博客

当然我肯定不是完全转载,我会把这个步骤给分解出来.

0.下载googletts并且放到preinstall目录(实现预安装程序,请八仙过海吧)

1.打上面的补丁,主要是为了让系统默认选中该语音为默认tts

2.烧录固件完成后,自己写个textSpeech例子,发现...播报不了. 插网线.

3.发现可以播报,完了就

adb pull /data/user_de/0/com.google.android.tts ./ 把这个文件夹下的app_voices_greco_v15保存好.你就不用去csdn下载各种XXXX语音包了. 当然,我用的apk比较老.所以是app_voices_greco_v15

可能最新是v16或者17 18说不定.这里只是提供一种不用去csdn下载的自行提取办法.

然后就在你的预安装脚本把这个文件夹push到任何你喜欢的目录.

4.第一次开机启动,cp -r 到/data/user_de/0/com.google.android.tts 并且chmod 777 -R .(至于是用什么apk来执行这个,还是搞个什么脚本随便你们八仙过海)

5.不插网线也可以正常使用.
