语言环境在印度尼西亚语，执行ota后出现的recovery界面，观察没有提示的字符，其他语言都有。
在 recovery.cpp 中这里打log
Device::BuiltinAction start_recovery(Device* device, const std::vector<std::string>& args) {
......
std::vector<std::string> title_lines =
android::base::Split(android::base::GetProperty("ro.bootimage.build.fingerprint", ""), ":");
title_lines.insert(std::begin(title_lines), "Android Recovery");
ui->SetTitle(title_lines);
ui->ResetKeyInterruptStatus();
device->StartRecovery();
printf("Command:");
for (const auto& arg : args) {
printf(" =====\"%s\"", arg.c_str());
}
printf("\n\n");
property_list(print_property, nullptr);
printf("\n");
ui->Print("Supported API: %d\n", kRecoveryApiVersion);
编译烧录，执行ota升级，再到recovery完成
adb pull cache/recovery/last_log C:\Users\xxx\Desktop\recovery
打开查看到如下图：输出的命令是 --locale=id-ID

对比settings中设置语言应该是 in-ID，
所以测试将语言--locale=id-ID 改成 --locale=in-ID
修改command 输入的地方修改语言成 in-ID
所以找到 RecoverySystem.java
public static void installPackage(Context context, File packageFile, boolean processed)
throws IOException {
......
final String filenameArg = "--update_package=" + filename + "\n";
String str = Locale.getDefault().toLanguageTag();
if(str.equals("id-ID")){
str = "in-ID";
}//fix for recovery ui ,show text
final String localeArg = "--locale=" + str + "\n";
final String securityArg = "--security\n";
......
}
最后测试，成功显示出来！
