Create Boot animation 

In given below example here will create bootanimation.zip file programmatically. In this example are first will create many jpeg files from a video file then will create part0 folder and desc.txt file again we will convert these part0 folders and desc.txt file in a bootanimation.zip file.

Change Boot animation programmatically

For change boot animation we will create ADB command programmatically. We can change boot animation two types because the bootanimation.zip file may exist in two location first one in /system/media/bootanimation.zip or in second /data/local/bootanimation.zip. 

First method

for change in first location /system/we will have to needed rooted device.

Runtime.getRuntime().exec(new String[] { "su", "-c","mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system/" });

Runtime.getRuntime().exec(new String[] { "su", "-c", "chmod 777 /system/" });

Runtime.getRuntime()

.exec(new String[] {"su","-c","cat "+ f + " > /system/media/bootanimation.zip" });

Toast.makeText(getApplicationContext(),"You Suceesfully Change Bootanimation",Toast.LENGTH_LONG).show();

Toast.makeText(getApplicationContext(), "Wait till boot.....",Toast.LENGTH_LONG).show();

new Handler().postDelayed(new Runnable() {

public void run() {

Runtime.getRuntime().exec(

new String[] { "su", "-c", "reboot" });

}

}, 20000);

} 

second method

for change in second location /data/local/bootanimation.zip, it is not the necessarily rooted device.

Runtime.getRuntime().exec(new String[] { "su", "-c","mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system/" });

Runtime.getRuntime().exec(new String[] { "su", "-c", "chmod 777 /system/" });

Runtime.getRuntime().exec(new String[] {"su","-c","cat "+ f + " > /data/local/bootanimation.zip" });

Toast.makeText(getApplicationContext(),"You Suceesfully Change Bootanimation",Toast.LENGTH_LONG).show();

Toast.makeText(getApplicationContext(), "Wait.....",Toast.LENGTH_LONG).show();

new Handler().postDelayed(new Runnable() {

public void run() {

Runtime.getRuntime().exec(

new String[] { "su", "-c", "reboot" });

}, 20000);

}
