I got issue with Nexus 10 - 4.2.2. I was testing code below on Galaxy Tab 10.1 with 4.0.4 and it was working fine:
try
{
Process proc = Runtime.getRuntime()
To show and hide the system bar and notification bar on 4.2.2 and others:
Hide:
try
{
String command;
command = "LD_LIBRARY_PATH=/vendor/lib:/system/lib service call activity 42 s16 com.android.systemui";
Process proc = Runtime.getRuntime().exec(new String[] { "su", "-c", command }, envp);
proc.waitFor();
}
catch(Exception ex)
{
Toast.makeText(getApplicationContext(), ex.getMessage(), Toast.LENGTH_LONG).show();
}
Show:
try
{
String command;
command = "LD_LIBRARY_PATH=/vendor/lib:/system/lib am startservice -n com.android.systemui/.SystemUIService";
Process proc = Runtime.getRuntime().exec(new String[] { "su", "-c", command }, envp);
proc.waitFor();
}
catch (Exception e)
{
e.printStackTrace();
}
