A collection of simple setup techniques in Android development _android

This example summarizes the simple setup techniques in Android development. Share to everyone for your reference, specific as follows:

1 Boot Picture:

Android-logo-mask.png
Android-logo-shine.png

These two pictures one in the previous next

./out/target/common/obj/java_libraries/android_stubs_current_intermediates/classes/assets/images/ Android-logo-shine.png
./frameworks/base/core/res/assets/images/android-logo-shine.png

Note: If the source code is not made, you can change the image directly in the frameworks.

Then direct make must be changed completely and cannot make only make Firmwar

2 The default boot wallpaper location:

Default_wallpaper.jpg

./out/target/common/obj/java_libraries/android_stubs_current_intermediates/classes/res/drawable/default_ Wallpaper.jpg
./frameworks/base/core/res/res/drawable/default_wallpaper.jpg

Note: This setting is the same as above and neither of them can change the filename

3 Change PC Machine Delete hardware text kernel

Drivers/usb/gadget/f_mass_storage.c

Fsg->vendor = "Xxxxxxxxxxxxx";

4 Change the volume label:

Bootable/recovery/etc/init.rc
SetProp Uservolumelabel "Xxxxxxxxxxxxx"

Package directly

5 Modify the Screen lock:

(1)

Frameworks/base/packages/settingsprovider/res/values/defaults.xml

<integer name= "Def_screen_off_timeout" >60000</integer>

60000 change to the desired time if it is not locked to-1

(2)

Frameworks/policies/base/phone/com/android/internal/policy/impl/keyguardviewmediator.java

Private Boolean mexternallyenabled = true;

Modify it to False

This change will no longer go into hibernation.

6 Initialization language:

Out\target\product\sdkdemo\root\default.prop
Rkdroid2.1\recovery\default.prop
Ro.product.locale.language = Es_es
Ro.product.locale.region = Es_es

Cannot make direct packaging

7 Set Initialization homepage:

Package/app/browser/res/values/string.xml

655 lines

The back is supposed to be in the bookmark.

8 Set Brightness 0~255:

Frameworks/base/packages/settingsprovider/res/values/defaults.xml

Def_screen_brightness--> This value is initialized like more than 100

9 Volume:

Frameworks/base/media/java/android/media/audiomanager.java
Array Default_stream_volume 4th value (Max I set to 30 but still 2 to the max-default is 11

It is recommended that all values in the array be set to the maximum OK.

MM Frameworks/base

10 Set up Google account , the upper left corner prompts "is setting RK2818SDK", the request is changed to "Setting W9":

13th line of Default.prop file in Out\target\product\sdkdemo\root

RO.PRODUCT.MODEL=RK2818SDK changed to Ro.product.model=w9

11 recordings are not shown in hours. Increased requirements:

Packages\apps\soundrecorder\src\com\android\soundrecorder
(1) Soundrecorder.java: private void Updatetimerview ()
Put

Copy Code code as follows:

String timestr = String.Format (Mtimerformat, TIME/60, time%60);

To

Long hour=time/3600;
String timestr = String.Format (Mtimerformat, Hour, (time-hour*3600)/60, time%60);

(2) in \res\values, Strings.xml should read:

<string name= "Timer_format" >
<xliff:g id= "format" >%02d:%02d:%02d</xliff:g>
</string >

12 Remove Bluetooth:

(Main interface-> Add Folder->bluetooth received)

Ic_launcher_folder_bluetooth.png (72*72):

In \packages\apps\bluetooth\res\drawable-hdpi
Workaround: Delete the bluetooth.apk under \out\target\product\sdkdemo\system\app

13 Charge lock Screen when the picture:

Frameworks\base\core\res\res\drawable-hdpi:ic_lock_idle_charging.png

14 Display the charge percentage when removing the lock screen:

FRAMEWORKS\BASE\CORE\RES\RES\VALUES-ZH-RCN the contents and parentheses of the strings.xml in the lockscreen_plugged_in bracket!!

15 Remove the Dynamic desktop background option:

Packages\wallpapers\basic Androidmanifest.xml <service> These, such as galaxies, are commented out as follows:

<service
  android:label= "@string/wallpaper_galaxy"
  android:name= " Com.android.wallpaper.galaxy.GalaxyWallpaper "
  android:permission=" Android.permission.BIND_WALLPAPER ">
  <intent-filter>
    <action android:name= "Android.service.wallpaper.WallpaperService"/>
  </intent-filter>
  <meta-data android:name= "Android.service.wallpaper" android:resource= "@xml/galaxy" />
</srvice>

16 Change version Number:

Build/core/makefile

79 lines

Rk_ver: = xxx

17 changing the layout of the interface

Location: Package/app/launcher2/res/xml/default_workspace.xml

Note: When you click on an arbitrary apk in the ADB shell, it will output in the background

I/activitymanager (728): Starting activity:intent {Act=android.intent.action.main cat=[ Android.intent.category.LAUNCHER] flg=0x10200000 Cmp=com.estrongs.android.pop/.view. Fileexploreractivity bnds=[294,373][393,478]}
I/windowmanager (728): Setting rotation to 1, animflags=0

Look at the blue part to find/front is the name of the package/back is the class name--> this is needed in default_workspace.xml.

Launcher:packagename= "Com.android.browser"       
launcher:classname= "com.android.browser.BrowserActivity"

18 How to put a PDF class file on the desktop

Customer requests that their own PDF help document be placed on the desktop so that guests can click to browse

String urlstring = "/SYSTEM/APP/NVSBL p4dv2 中文版 manual.pdf";
Intent Intent = new Intent ();
Intent.setaction (Android.content.Intent.ACTION_VIEW);
Intent.setdataandtype (Uri.fromfile (New File (urlstring)), "Application/pdf");
StartActivity (intent);
Finish ();

Explained below:

First put the PDF document under Out/target/product/sdkdemo/system/app

Give the fixed address to the urlstring, use the intent

Intent.setaction (Android.content.Intent.ACTION_VIEW);

Start view

Intent.setdataandtype (Uri.fromfile (New File (urlstring)), "application/pdf");

Application/pdf can specify other formats including audio, video, pictures, etc. but not tried.

Note: This method is not very good if you just place a few pictures, but if you put the files in a larger size, then package them.

System.img files can be very large, which is to occupy the system memory-----> so it is not recommended to use!!!!!!!!!!!
