Android Question help please

Check the java 8 Version and be sure to set the right paths in Tools configure Paths.
Maybe update your java....

1. Java JDK v8

• Open the Java 8 JDK download link.
• Check the Accept License Agreement button.
• Select "Windows x86 (32-bit) or Windows x64" in the platforms list.
• Download the file and install it.

Also make sure to setup B4A correctly:

3. B4A

• Download B4A Trial Version
• Open B4A.
• Choose Tools > Configure Paths.
• Set the path to "javac.exe" if it is empty (C:\Program Files\Java\jdk1.8.0_102\bin\javac.exe).
• Click on Open Sdk Manager button.
• Set the path to "sdkmanager.bat" (C:\Android\tools\bin\sdkmanager.bat) and install all recommended items.
• Read and accept the licenses when asked for.
• Return to B4A and set the path to "android.jar" (C:\Android\platforms\android-27\android.jar).
  

Hello DONMANFRED and thanks for answering, I followed all the installation instructions only I install the jdk version 9.0.1 is that a problem if the latest version is installed?, apparently the code is compiled without any error, but when B4A trying to install it on the device previously connected through the B4A-Bridge marks the error mentioned in my first post In both the state shows that they are connected. also when trying to connect the designer I get this error: An error has occurred. The system can not find the specified file Restarting the ADB Server can solve this problem Tools- Restart ADB Server. I do not know if these errors are linked to the same problem?

forget to mention that I have installed the registered version B4A 7.80

What device are you trying to run the software on and what is the version of Android on the device?

Can you post the full text from the compilation window?

Hi, the device is a tablet brand necnon 10 inch, android version 4.0.4, thanks all you guys for the help.

It looks like a problem with Android SDK.

Try to reinstall a new SDK in a new folder and configure the IDE to use it.
Follow these instructions: https://www.b4x.com/b4a.html
