- the average of all records from database
- the minimum and maximum values that occurred these past three days.

DIY¶
Do it Yourself (DIY) your own kivy app!
Note
This guide was developed on OSX 10.9.5, python 2.7, kivy 1.8.1
- brew install dpkg
- vi .bash_profile and comment this line
#export ARCHFLAGS = “-arch x86”
- create your app - main.py
- save your dir in your home
` /Users/usuario/dir
`
3. init buildozer
` dir usuario$ buildozer init
`
4. modified the buildozer spec file
` dir usuario$ vi buildozer.spec
`
5. create a virtualenv in your dir
` dir usuario$ virtualenv venv --distribute
`
6. activate virtualenv
` dir usuario$ source /venv/bin/activate
`
.. note:
to deactivate :
dir usuario$ deactivate
- run buildozer - see more in : https://github.com/kivy/buildozer
` dir usuario$ buildozer android release
`
Signed and Zipalign¶
More infos to create a signature and to zip in : https://github.com/kivy/kivy/wiki/Creating-a-Release-APK
- change the dir
` dir usuario$ cd ~
`
2. Obtain a keystore
- ```
- keytool -genkey -v -keystore ./keystores/<my-new-key>.keystore -alias <my-alias> -keyalg RSA -keysize 2048 -validity 10000
``` 3. then signed as follows
- ```
- jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore ./keystores/<my-new-key>.keystore ./<my-project>/bin/<MyProject>-<version>-release-unsigned.apk <my-alias>
``` 4. zip the apk already signed
- ```
- .buildozer/android/platform/android-sdk-21/build-tools/21.1.1/zipalign -v 4 ./<my-project>/bin/<MyProject>-<version>-release-unsigned.apk ./<my-project>/bin/<MyProject>.apk
``` .. warning:
The zipalign script may not be in tools, but you can also find it in build-tools.
adb logcat and installation on android¶
- change to dir
` cd /Users/usuario/.buildozer/android/platform/android-sdk-21/platform-tools
`
- install device
` platform-tools usuario$ ./adb start-serve
`
` platform-tools usuario$ ./adb devices
`
- adb install the apk on android for test
` platform-tools usuario$ ./adb install /Users/usuario/dir/bin/<app-name>.apk
`
4. see error log
