− | ==Code Samples==
| + | |
− | * Here is a github address for code samples: https://github.com/friendlyarm/AndroidHardwareAccess
| + | |
− | | + | |
− | ==Compile & Deploy Andorid Code (SerialPortDemo)==
| + | |
− | ===Step 1. Import source code in eclipse (SerialPortDemo)===
| + | |
− | Start eclipse, click on "Import" on its main window's File menu and then select "Existing Android Code Into Workspace" to import your source code<br />
| + | |
− | We name this project as "SerialPortDemo"<br />
| + | |
− | | + | |
− | <div><ul>
| + | |
− | <li style="display: inline-block;">[[File:AndroidHW01.png|400px]]</li>
| + | |
− | <li style="display: inline-block;">[[File:AndroidHW02.png|400px]] </li>
| + | |
− | </ul></div>
| + | |
− | | + | |
− | ===Step 2. Edit source code===
| + | |
− | The names of serial devices this DEMO accesses are listed in this file: src/com/friendlyarm/SerialPortDemo/SerialPortDataProcessView.java<br /> | + | |
− | Make changes according to your devices' names:<br />
| + | |
− | [[File:AndroidHW03.png|500px]]<br />
| + | |
− | | + | |
− | ====Serial Device Names under Multiple Platforms====
| + | |
− | * Allwinner H3/H5 Based Boards (NanoPi M1/NanoPi M1 Plus etc)
| + | |
− | UART1-> /dev/ttyS1<br />
| + | |
− | UART2 -> /dev/ttyS2<br />
| + | |
− | UART3 -> /dev/ttyS3 (Only applies to NanoPi M1, NanoPi K1 and NanoPi K1 Plus)<br />
| + | |
− | | + | |
− | * S5P4418 Based Boards (NanoPi Fire2A/NanoPi M2A/NanoPi S2/NanoPC-T2 etc)
| + | |
− | UART1 -> /dev/ttyAMA1 [Note 1]<br />
| + | |
− | UART2 -> /dev/ttyAMA2 [Note 1]<br />
| + | |
− | UART3 -> /dev/ttyAMA3<br />
| + | |
− | UART4 -> /dev/ttyAMA4<br />
| + | |
− | | + | |
− | * S5P6818 Based Boards (NanoPi M3/NanoPC-T3 etc)
| + | |
− | UART1 -> /dev/ttySAC1 [Note 1]<br />
| + | |
− | UART2 -> /dev/ttySAC2 [Note 1]<br />
| + | |
− | UART3 -> /dev/ttySAC3<br />
| + | |
− | UART4 -> /dev/ttySAC4<br />
| + | |
− | <br />
| + | |
− | Note 1: only applies to specific boards, you need to check if a board has that serial device populated.
| + | |
− | | + | |
− | ===Step 3. Compile DEMO's source code and export apk file===
| + | |
− | On "Package Explorer" check your project's name:<br />
| + | |
− | [[File:AndroidHW04.png|500px]]<br />
| + | |
− | On eclipse's main menu select "File" and then "Export...":<br />
| + | |
− | [[File:AndroidHW05.png|500px]]<br />
| + | |
− | Select "Export Android Application":<br />
| + | |
− | [[File:AndroidHW06.png|500px]]<br />
| + | |
− | Select "SerialPortDemo":<br />
| + | |
− | [[File:AndroidHW07.png|500px]]<br />
| + | |
− | Eclipse requires you to create a new keystore or select an existing keysotre in this step. In this case we selected "Create new keystore", set a path to store the key and created its password and then clicked on "next":<br />
| + | |
− | [[File:AndroidHW08.png|500px]]<br /> | + | |
− | Refer to the following screenshot to fill more information and click on "next":<br />
| + | |
− | [[File:AndroidHW09.png|500px]]<br />
| + | |
− | Select a path to store your APK file. In this case we set it to a "signapk-files" directory:<br />
| + | |
− | [[File:AndroidHW10.png|500px]]<br />
| + | |
− | Click on "Finish" to export an APK file.<br />
| + | |
− | [[File:AndroidHW11.png|500px]]
| + | |
− | ===Step 4. Give APK New Signature===
| + | |
− | For a program to access a hardware device that program needs to have "system" right therefore you need to give your APK a new signature.<br />
| + | |
− | Enter the signapk-files directory and give your APK a new signature:
| + | |
− | <syntaxhighlight lang="bash">
| + | |
− | cd signapk-files/
| + | |
− | java -jar ./signapk.jar platform.x509.pem platform.pk8 ./SerialPortDemo.apk SerialPortDemo-Signed.apk
| + | |
− | </syntaxhighlight>
| + | |
− | The "signapk.jar", "platform.x509.pem" and "platform.pk8" files are available under the "android-platform-key-files" directory.
| + | |
− | | + | |
− | ===Step 5 Run & Debug===
| + | |
− | 5.1) Install APK. Connect your board to a host PC with a microUSB cable and run adb commands to install your "SerialPortDemo-Signed.apk":
| + | |
− | <syntaxhighlight lang="bash">
| + | |
− | adb install SerialPortDemo-Signed.apk
| + | |
− | </syntaxhighlight>
| + | |
− | | + | |
− | 5.2) Debug:
| + | |
− | After SerialPortDemo is started run the following command in "adb shell":
| + | |
− | <syntaxhighlight lang="bash">
| + | |
− | ps -Z
| + | |
− | </syntaxhighlight>
| + | |
− | Check this com.friendlyarm.SerialPortDemo" process. If its right is as follows that means this application already has "system" right:
| + | |
− | <syntaxhighlight lang="bash">
| + | |
− | u:r:system_app:s0 system 1610 112 com.friendlyarm.SerialPortDemo
| + | |
− | </syntaxhighlight>
| + | |
− | This case is for Android 4. If you do it under Android 5 it will be as follows. Although some details are slightly different it means the application has "system" right as well:
| + | |
− | <syntaxhighlight lang="bash">
| + | |
− | u:r:platform_app:s0 u0_a60 1905 138 com.friendlyarm.SerialPortDemo
| + | |
− | </syntaxhighlight>
| + | |
− | If your application doesn't have "system" right it will fail to open a device.
