Android things: DP 7 retired PeripheralManagerService and I have issue with PeripheralManager



I have 1 project based on this: https://github.com/Nilhcem/i2cfun-androidthings
https://github.com/neuberfran/SmartDrive5 (the latter is my project)



But, when I change PeripheralManagerService to PeripheralManager (DP 7 and APi level 27)


try {
PeripheralManager manager = PeripheralManager.getInstance();
mDevice = manager.openI2cDevice(I2C_DEVICE_NAME, I2C_ADDRESS);
} catch (IOException e) {
Log.w(TAG, "Unable to access I2C device", e);
}



I have this issue: https://drive.google.com/file/d/1kXfknYcu4RUF7AT1549_sjJiVSG2_Jjo/view?usp=sharing in this line: https://drive.google.com/file/d/1nTXOV0qiQDe5XldzIuLsY26oIdyfs3x3/view?usp=sharing



I know about this: PeripheralManagerService throws NoClassDefFoundError
but not solved.



Can you help me





You should update your device operating system and the library to version 1.0.0 as a number of APIs have changed or been updated.

@NickFelker How to I do this without necessarily pulling another install image and burning a sd card?

If you're still on the developer preview, your best bet is to install a new image. After that you'll be able to create new images and OTA update them to the device.

@NickFelker I create: OS version 1.0.1 (latest). I can run motors with pio i2c I2C1 0x1B write-raw 0x46 128 0x05 0x00 0xD1. But 1.0.1 not exist and compileOnly 'com.google.android.things:androidthings:1.0' I have this issue: drive.google.com/file/d/1OeDRh23QEr0utkWrDglhI9iNjS4Z6ABS/… drive.google.com/file/d/10hCYyfJ0PGw0QflMiVjc12f-7B9h0Ryz/…

compileOnly 'com.google.android.things:androidthings:1.0' is the latest dependency. As you're seeing the permissions issue, you should add the permission to your manifest and then install the app again and then do a reboot.

The class not found exception means that peripheral manager is not on the operating system. You are trying to use a new API on a device that has an older version.



You need to have the Android things library dependency in sync with the version installed on your device.



And as it has been suggested, you should get everything into the stable release.

PHP contact form sending but not receiving emails I have created a contact form using PHP to send the data. The form seems to send fine as there are no errors and success message appears, however I am not receving the emails into the designated inbox. I am using PHPMailer as I originally tried just using the php 'mail' command which I now understand is a bit hit and miss. I cannot see why I would not be receving the emails so I would be very grateful for any help that could be given. I'm quite new to PHP so please be patient with me :) <?php use PHPMailerPHPMailerPHPMailer; use PHPMailerPHPMailerException; $msg = ""; if (isset($_POST['submit'])) { require 'phpmailer/src/Exception.php'; require 'phpmailer/src/PHPMailer.php'; require 'phpmailer/src/SMTP.php'; function sendemail ($to, $from, $body) { $mail = new PHPMailer(true); $mail->setFrom($from); $mail->addAddress($to); $ma...

Do graphics cards have individual ID by which single devices can be distinguished?

Do graphics cards have individual ID by which single devices can be distinguished? I have several graphics cards of the same manufacturer and same model and I want to distinguish them not only by the pcie socket they reside in but by some individual value I can read from the hardware. Is there such value and if so what would it be called and how could I access it? Right now I'm using modern nvidia cards (10xx series) and nvidia inspector.but I'd prefer if there was any value that was also applicable to amd. I have programming and scripting knowledge. I am running Windows 10 1 Answer 1 This is a powershell example to pull information from video cards. The DeviceID is supposed to be unique but only if the manufacturer supports Windows Display Driver Model (WDDM). (I copied this directly from docs.microsoft.com) $strComputer = "." $colItems = get-wmiobject -class "Win32_VideoC...
