// #endif7.增加自定义系统按键
device/qcom/common/base.mk
KEYPAD += aaaaa.kl
device/qcom/msm8953_64/AndroidBoard.mk
include $(CLEAR_VARS)
LOCAL_MODULE := aaaaa.kl
LOCAL_MODULE_TAGS := optional eng
LOCAL_MODULE_CLASS := ETC
LOCAL_SRC_FILES := $(LOCAL_MODULE)
LOCAL_MODULE_PATH := $(TARGET_OUT_KEYLAYOUT)
include $(BUILD_PREBUILT)
device/qcom/msmxxx/aaaaa.kl
key 0x17b BACK_CAMERA
key 0x21e ILL_LIGHT
key 0x74 POWERframeworks/native/include/input/InputEventLabels.h
DEFINE_KEYCODE(BACK_CAMERA),
DEFINE_KEYCODE(ILL_LIGHT),
frameworks/native/include/android/keycodes.h
AKEYCODE_BACK_CAMERA = 284,
AKEYCODE_ILL_LIGHT = 285
frameworks/base/core/res/res/xml/global_keys.xml
8. user 支持 fastboot
bootable/bootloader/lk/makefile
#ifeq ($(TARGET_BUILD_VARIANT),user)
# CFLAGS += -DDISABLE_FASTBOOT_CMDS=1
#endif9.修改Telephony.getDeviceId 返回IMEI
frameworks/base/telephony/java/android/telephony/TelephonyManager.java
/*public String getDeviceId(int slotId) {
android.util.SeempLog.record_str(8, ""+slotId);
// FIXME this assumes phoneId == slotId
try {
IPhoneSubInfo info = getSubscriberInfo();
if (info == null)
return null;
return info.getDeviceIdForPhone(slotId, mContext.getOpPackageName());
} catch (RemoteException ex) {
return null;
} catch (NullPointerException ex) {
return null;
}
}*/
public String getDeviceId(int slotId) {
ITelephony telephony = getITelephony();
if (telephony == null) return null;
try {
return telephony.getImeiForSlot(slotId, getOpPackageName());
} catch (RemoteException ex) {
return null;
} catch (NullPointerException ex) {
return null;
}
}10.修改开机提示无网络问题 或者网络图标问题
frameworks/base/services/core/java/com/android/server/connectivity/NetworkMonitor.java
//private static final String DEFAULT_HTTPS_URL = "https://www.google.com/generate_204";
//private static final String DEFAULT_HTTP_URL =
// "http://connectivitycheck.gstatic.com/generate_204";
//private static final String DEFAULT_FALLBACK_URL = "http://www.google.com/gen_204";
private static final String DEFAULT_HTTPS_URL = "https://www.qualcomm.cn/generate_204";
private static final String DEFAULT_HTTP_URL =
"http://www.qualcomm.cn/generate_204";
private static final String DEFAULT_FALLBACK_URL = "http://www.qualcomm.cn/generate_204";11 .删除检查com.google.android.gms
frameworks/base/services/core/java/com/android/server/PersistentDataBlockService.java
private int getAllowedUid(int userHandle) {
//String allowedPackage = mContext.getResources()
// .getString(R.string.config_persistentDataPackageName);
//PackageManager pm = mContext.getPackageManager();
int allowedUid = -1;
/*try {
allowedUid = pm.getPackageUidAsUser(allowedPackage,
PackageManager.MATCH_SYSTEM_ONLY, userHandle);
} catch (PackageManager.NameNotFoundException e) {
// not expected
Slog.e(TAG, "not able to find package " + allowedPackage, e);
}*/
return allowedUid;
}11 .在启动时启动警告消息服务
packages/apps/Settings/src/com/android/settings/FallbackHome.java
private void maybeFinish() {
if (getSystemService(UserManager.class).isUserUnlocked()) {
final Intent homeIntent = new Intent(Intent.ACTION_MAIN)
.addCategory(Intent.CATEGORY_HOME);
final ResolveInfo homeInfo = getPackageManager().resolveActivity(homeIntent, 0);
if (Objects.equals(getPackageName(), homeInfo.activityInfo.packageName)) {
Log.d(TAG, "User unlocked but no home; let's hope someone enables one soon?");
mHandler.sendEmptyMessageDelayed(0, 500);
} else {
Log.d(TAG, "User unlocked and real home found; let's go!");
//add code
Intent warningIntent = new Intent();
warningIntent.setPackage("com.pvetec.warningmessage");
warningIntent.setAction("pvetec.intent.action.boot.disclaimer.service.start");
startService(warningIntent);
//add code
getSystemService(PowerManager.class).userActivity(
SystemClock.uptimeMillis(), false);
finish();
}
}
12 .用emmc和usbotg挂载路径
system/vold/PublicVolume.cpp
idx = msyspath.find("2-1.2");
if(idx == std::string::npos){
} else {
stableName = "usbotg-2-1.2";
}
idx = msyspath.find("mmc1:0002");
if(idx == std::string::npos){
} else {
stableName = "mmc1-0002";
}13 .usb3.0和usb2.0设备安装路径
system/vold/PublicVolume.cpp
idx = msyspath.find("xhci-hcd.0.auto/usb");
if(idx == std::string::npos){
} else {
stableName = "usbotg-2-1.2";
}
idx = msyspath.find("mmc1:");
if(idx == std::string::npos){
} else {
stableName = "mmc1-0002";
}
