The upgrade of Ubuntu results in an error in the compilation of Android Jack [Two Method to Solve]

Error log:

Problems caused by JDK automatic upgrade

Method 1:

Delete tlsv1 and tlsv1.1 under jdk.tls.disabledalgorithms in/etc/java-8-openjdk/security/java.security

Then install Jack again  （ Jack needs to modify the port number after unloading and reloading)

It needs to be implemented

jack-admin   uninstall-server  & amp;& amp;   jack-admin   kill-server
make   setup-jack-server

Then reinstall jack (you need to change the port number after jack uninstall and reinstall)
You need to execute

make setup-jack-server

Encryption unsuccessful, need to factory reset or crash after android restarts several times

This reality has been seen in previous projects that did not have batteries, but the one that did not have a battery power outage and had data being written to EMMC, whereas reboot was supposed to shut down or pause all threads to make sure that no EMMC operation was written. Depressing.
There is no way to appear, it appears, take a look at what Android Reboot does, baidu, there are a lot of, post the process out:

framework 
./base/core/java/com/android/internal/app/ShutdownThread.java

     * Do not call this directly. Use {@link #reboot(Context, String, boolean)}
     * or {@link #shutdown(Context, boolean)} instead.
     *

     * @param reason reason for reboot
     */
    public static void rebootOrShutdown(boolean reboot, String reason) {
        if (reboot) {
            Log.i(TAG, "Rebooting, reason: " + reason);
            try {
                Power.reboot(reason);
            } catch (Exception e) {
                Log.e(TAG, "Reboot failed, will attempt shutdown instead", e);
            }
        } else if (SHUTDOWN_VIBRATE_MS > 0) {
            // vibrate before shutting down
            Vibrator vibrator = new Vibrator();
            try {
                vibrator.vibrate(SHUTDOWN_VIBRATE_MS);
            } catch (Exception e) {
                // Failure to vibrate shouldn't interrupt shutdown.  Just log it.
                Log.w(TAG, "Failed to vibrate during shutdown.", e);
            }

            // vibrator is asynchronous so we need to wait to avoid shutting down too soon.
            try {
                Thread.sleep(SHUTDOWN_VIBRATE_MS);
            } catch (InterruptedException unused) {
            }
        }

        // Shutdown power
        Log.i(TAG, "Performing low-level shutdown...");
        Power.shutdown();
    }

    jniThrowIOException(env, errno);

	return 0;

}

as you can see from above, the system is mount readonly before reboot:

  remount_ro();

So why is there a problem?The problem seems to be remount_ro(); The inside. Look at the code inside

static void remount_ro(void)
{
    int fd, cnt = 0;

    /* Trigger the remount of the filesystems as read-only,
     * which also marks them clean.
     */
    fd = open("/proc/sysrq-trigger", O_WRONLY);
    if (fd < 0) {
        return;
    }
    write(fd, "u", 1);
    close(fd);


    /* Now poll /proc/mounts till it's done */
    while (!remount_ro_done() && (cnt < 50)) {
        usleep(100000);
        cnt++;
    }

    return;
}

 

/proc/sysrq-trigger

This is a read-only node that can restart the system, remount, and so on, but it’s asynchronous, so there’s a check and wait, it’s probably not long enough to wait (5S), let’s try it out for a minute.
