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"; }
