Hi. Sorry bit of a phone gap noob. When building this app with build.phonegap.com can I just add this plugin to the config.xml file, rather than installing the plugin using the CLI. As shown here: http://docs.build.phonegap.com/en_US/configuring_plugins.md.html#Plugins

@brodybits

Yes that should work. If not you can file an issue.

SQLitePlugin.java should have been installed in src/io/liteglue

Caused by: java.lang.UnsatisfiedLinkError: Couldn't load sqlc-native-driver from loader dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/com.ionicframework.testplugin2382207-1.apk"],nativeLibraryDirectories=[/data/app-lib/com.ionicframework.testplugin2382207-1, /system/lib]]]: findLibrary returned null But, I have added the sqlite - native - driver. Jar file

Christopher J. Brody

@brodybits

You may have to extract the contents of the lib subdirectory of sqlite-native-driver.jar into your libs directory, and remove sqlite-native-driver.jar from your project

@lyric123123

How to extract the sqlite - native - driver lib subdirectory of the content.

Christopher J. Brody

@brodybits

jar xf sqlite-native-driver.jar

then do something like mv lib/* libs

lyric123123

@lyric123123

Why can't directly use sqlite - native - driver. jar? I am a beginner, don't know the inside of the principle.

Christopher J. Brody

@brodybits

It should be possible but certain Android implementations do not expect it

Let me correct it. This is normal for regular Java, but Android is not regular Java. Android takes regular Java class files and converts them to DEX format before making the APK.

lyric123123

@lyric123123

Excuse me, where is your ever using Cordova sqlite-storage small demo of success ,android.

Christopher J. Brody

@brodybits

Hundreds, maybe thousands of apps already using it!

lyric123123

@lyric123123

I know

Christopher J. Brody

@brodybits

How do you create the app? Are you using the cordova cli or something else?

If you are having trouble, it is best to start with an extremely simple test, such as what I put in README.md.

lyric123123

@lyric123123

Ionic + cordova ,but this is an extremely simple test.

Christopher J. Brody

@brodybits

Aah yes. Ionic, which I think you know is basically a version of Angular with the UI framework, can be a pain to use with Cordova. They have ngCordova.

There was a very helpful article last year: https://blog.nraboy.com/2014/11/use-sqlite-instead-local-storage-ionic-framework/

@lyric123123

Thanks

lyric123123

@lyric123123

At the same mistake again.

I downloaded the zip file from that site (the link is at the top right), then extracted the two files in the folder (src/android/libs) and placed them in the project's libs directory. Then, I refreshed the project.

As the error kept going, he told me to "Make sure you removed sqlite-native-driver.jar". I deleted that file from the libs directory, refreshed the project, and The following error.

then

lyric123123

@lyric123123

The same error, add the jar is not effective.

Christopher J. Brody

@brodybits

You have to remove sqlite-native-driver.jar

and make sure you install the native libraries in your libs directory instead

lyric123123

@lyric123123

How to install the native libraries in my libs directory.

Christopher J. Brody

@brodybits

You have to do jar xf sqlite-native-driver.jar to extract it.

You will get a lib directory

You have to move all the subdirectories from the lib directory into your libs directory

I need to fix this very soon!

lyric123123

@lyric123123

OK, thanks.

@shizhidi

i want to know, where is the *.db file,I see no file on your mobile phone.

Who knows?

my phone

@peter279k

Hi.If you use adt-bundle ,and you can open the DDMS.
then open the file explorer and choose following path data/data/com.example.name.your-app-name/databases/your-db-name.db

Christopher J. Brody

@brodybits

Thanks @peter279k. Yes for Android, external applications cannot see your database file unless you root your device (which I do not recommend). This should be documented, when I get a chance.

Hi everyone! I am trying to make foreign key in table, but it does not work. Are you include such functionality in your plugin? Maybe you have some examples? Thanks.

Please post this question with a demo program at https://github.com/litehelpers/Cordova-sqlite-storage/issues or https://github.com/litehelpers/Cordova-sqlite-help/issues

@laoyao

@brodybits Is there any tool to open the encryptped sqlite file?

I am using the Cordova-sqlcipher-adapter plugin encrypt the sqlite file

Christopher J. Brody

@brodybits

The sqlcipher project itself includes a CLI tool that can be used to open your encrypted database file and execute some queries. Works just like the sqlite CLI tool.
