Steps to create an apk file using ionic 3
Step1: Add Platform
$ ionic cordova add platform android
Step 2: Go to platforms/android
$ cd platforms/android
Note: Add the location of the bin folder of the JDK installation in the PATH Environment Variable
Step 3: Generate Keystore file
$ keytool -genkey -v -keystore some_name.keystore -alias some_name-keyalg RSA -keysize 2048 -validity 10000
You should enter a password during the generation of some_name.keystore. Remember this passoword and keep some_name.keystore in a safe place.
Step 4: Open build.gradle file in platforms/android and search for the section signingConfigs. Make changes as shown below.
signingConfigs {
release {
// These must be set or Gradle will complain (even if they are overridden).
keyAlias = "some_name"
keyPassword = "your_password" // And these must be set to non-empty in order to have the signing step added to the task graph.
storeFile = "some_name.keystore"
storePassword = "your_password"
}
}
Step 5: Go to your root folder of the project
$ cd ../../
Step 6: Build
$ ionic cordova build android --release
If successful you will get the following message

Step 7: Sign the apk
$ jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore platforms\android\some_name.keystore platforms\android\build\outputs\apk\android-release-unsigned.apk some_name
Note: Add the location of the Android sdk build tools folder in the PATH Environment Variable.

ReplyDeleteWhat style shoe should I wear? Is this my correct size? How can I tell if the shoes are really well made? These questions and many more must be answered each time a pair of shoes is selected and bought. Giày Balenciaga speed trainer
ReplyDeleteShoes are an essential fashion accessory for both men and women alike. It is important that we have a few pair of shoes that are considered essential for our daily use. These include, formal shoes (preferably black or brown), casual shoes, walking shoes and running shoes. When shopping for shoes, you should always choose the best, for the sake of your feet, and choose something that you can wear for different occasions. Designer shoes are always the best choice, especially when it comes to buying shoes for your personal use (as opposed to just gifts). Giày MLB
