公司最近来了一批四核的平板，刚开始以为是四核平板和二核平板的差异，导致systembar不能隐藏和正常显示。经过调查才发现，是android系统的版本问题。知道问题的所在，解决起来也就快了。

 public void showSystembar(boolean makeVisible) {        checkInitialized();        try {            // get the existing environment            ArrayList<String> envlist = new ArrayList<String>();            Map<String, String> env = System.getenv();            for (String envName : env.keySet()) {                envlist.add(envName + "=" + env.get(envName));            }            String[] envp = (String[]) envlist.toArray(new String[0]);            // depending on makeVisible, show or hide the bar            if (makeVisible) {                Log.v(TAG, "showBar will show systembar");                // execute in correct environment                String command;                Device dev = Device.getInstance();                if (dev.getAndroidVersion() == AndroidVersion.HC) {                    command = "LD_LIBRARY_PATH=/vendor/lib:/system/lib am startservice -n com.android.systemui/.SystemUIService";                //The four nucleus Tablet hide or display systemui                } else if(dev.getAndroidVersion() == AndroidVersion.JELLYBEAN4_2) {                    command = "su -c am startservice -n com.android.systemui/.SystemUIService ";                //The four nucleus Tablet hide or display systemui                } else {                    command = "rm /sdcard/hidebar-lock\n"                            + "sleep 5\n"                            + "LD_LIBRARY_PATH=/vendor/lib:/system/lib am startservice -n com.android.systemui/.SystemUIService";                }                //The four nucleus Tablet hide or display systemui                if(dev.getAndroidVersion() == AndroidVersion.JELLYBEAN4_2) {                Runtime.getRuntime().exec(command);                } else{                 Runtime.getRuntime().exec(new String[] { "su", "-c", command }, envp);                }                //The four nucleus Tablet hide or display systemui                // no proc.waitFor();                // we just shown the bar, set flag to visible                mSystembarVisible = true;            } else {                Log.v(TAG, "showBar will hide the systembar");                // execute in correct environment                String command;                Device dev = Device.getInstance();                if (dev.getAndroidVersion() == AndroidVersion.HC) {                    command = "LD_LIBRARY_PATH=/vendor/lib:/system/lib service call activity 79 s16 com.android.systemui";                //The four nucleus Tablet hide or display systemui                } else if(dev.getAndroidVersion() == AndroidVersion.JELLYBEAN4_2) {                    command = "su -c service call activity 42 s16 com.android.systemui";                //The four nucleus Tablet hide or display systemui                } else {                    command = "touch /sdcard/hidebar-lock\n"                            + "while [ -f /sdcard/hidebar-lock ]\n"                            + "do\n"                            + "killall com.android.systemui\n"//                            + "sleep 1\n"                            + "usleep 500000\n"                            + "done\n"                            + "LD_LIBRARY_PATH=/vendor/lib:/system/lib am startservice -n com.android.systemui/.SystemUIService";                }                //The four nucleus Tablet hide or display systemui                if(dev.getAndroidVersion() == AndroidVersion.JELLYBEAN4_2) {                Runtime.getRuntime().exec(command);                } else{                 Runtime.getRuntime().exec(new String[] { "su", "-c", command }, envp);                }                //The four nucleus Tablet hide or display systemui                // no proc.waitFor();                // we just hide the bar, set flag to not visible                mSystembarVisible = false;            }        } catch (Exception e) {            e.printStackTrace();        }    }

其他的方法：

    public enum AndroidVersion {    //The four nucleus Tablet hide or display systemui        HC, ICS, JB, JELLYBEAN4_2, UNKNOWN        //The four nucleus Tablet hide or display systemui    };    public AndroidVersion getAndroidVersion() {        checkInitialized();        Log.v(TAG, "getAndroidVersion called");        int sdk = android.os.Build.VERSION.SDK_INT;        if (11 <= sdk && sdk <= 13) {            Log.v(TAG, "We are running on HoneyComb");            return AndroidVersion.HC;        } else if (14 <= sdk && sdk <= 15) {            Log.v(TAG, "We are running on IceCreamSandwich");            return AndroidVersion.ICS;        } else if (16 == sdk) {            Log.v(TAG, "We are running on JellyBean");            return AndroidVersion.JB;        //The four nucleus Tablet hide or display systemui        } else if(17 <= sdk) {        Log.v(TAG, "We are running on JellyBean4.2");            return AndroidVersion.JELLYBEAN4_2;        //The four nucleus Tablet hide or display systemui        } else {            Log.v(TAG, "We don't know what we are running on");            return AndroidVersion.UNKNOWN;        }    }

记录一下。嘿嘿。。。
