2. Summary: 2.1 replace the boot Logo and boot Animation

Replace bootLogo

Device/amlogic/g18ref/res_pack

Replace the boot Animation

Make an on-premise animation, and set the relevant items as needed (1). Open the animation file bootanimation.zip and put it in the following directory of the patch package: device/amlogic/g18ref

 

 

2.2 The customer's pumpkin bookstore is set to the default Launcher;

Add the following two lines of code to the AndroidManifest. xml file in the source file of the pumpkin bookstore;

<Intent-filter>

<Category android: name = "android. intent. category. HOME"/>

<Category android: name = "android. intent. category. DEFAULT"/>

2.3 Pre-install the third-party input method and set it to the default value

Configure the System Default Input Method

Find the Ottsetting source file BootCompletedReceiverAML. java and add

 

Settings. Secure. putString (context. getContentResolver (), Settings. Secure. DEFAULT_INPUT_METHOD, "com. mipt. inputmethod. pinyin/. MiptIME ");

 

Library files on which the input method depends:

Symptom:

If you use a udisk to install miptime.apk, the system can normally use its input method, which is placed in the preinstall/app directory. The input method is not normal. Why?

Cause analysis:

Pre-installed apk files are placed in the preinstall directory. These apk files are directly copied to the/system/app/* directory, and the dependent library files are not automatically installed under the relevant directory,

Solution:

(1 when the serial print shows the prompt missing library file libjni_remoteime.sodecompress miptime.apk, take out the corresponding library file and pre-install it in system/lib

(2)MiptIME.apk put 5 ihome/vendor/amlogic/prebuilt/preinstallation. The apk file under the preinstalltion directory will automatically install the apk file under the directory when the network set-top box is started, the corresponding library files will also be installed under the corresponding file directory. (Recommended)

2.4 port OttSetting source code to the custom directory for compilation

Symptom:

However, the system prompts that the definition of some variables is missing,

Cause analysis:

Ask a colleague and find that there are some common variables in the frameworks layer that are used if they are not defined. Record the undefined variables prompted.

Solution:

Use ack-grep in the project before transplantation to find the variables defined in framwork and port them to framwork in 5iHome.
