还是@zoujunhua86给力，正如军华大神所说，一开始就定位错了..
经对比framework.jar.out/smali/android/preference/RingtonePreference.smali 发现多了如下内容
const-string v2, “android.intent.action.TY_RINGTONE_PICKER”
invoke-virtual {v0, v2}, Landroid/content/Intent;->setAction(Ljava/lang/String;)Landroid/content/Intent;
这也就符合了第三行的解释
E/AndroidRuntime( 784): android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.TY_RINGTONE_PICKER (has extras) }
android.intent.action.TY_RINGTONE_PICKER是额外增加了

E/AndroidRuntime( 784): at dalvik.system.NativeStart.main(Native Method)首先根据这个log定位到RingtonePreference.onClick(RingtonePreference.java:145)有问题
为什么不是出错log的第一行？
因为第一行是安卓基础库，一般不会出问题，是调用者有误。这里涉及到一点安卓知识，但是我不想展开，只需要对比bosp和厂商的文件，哪个文件？
android.preference.RingtonePreference.onClick(RingtonePreference.java:145)表示
在RingtonePreference.smali中（也可能在其他形如RingtonePreference$1.smali文件中）路径：framework.jar.out中，android.preference表示在framework.jar.out/android/preference目录下（找不到或者不会看，可以使用find命令），
(RingtonePreference.java:145)表示RingtonePreference文件的145行，对应smali中就是.line 145下的语句，
.onClick表示处于这个文件的onClick方法内对比bosp和厂商的这两个方法，我推断TY，可能是天语应该是改动这个文件，bosp是安卓标准文件，改成bosp的即可
