# Crash handler
A Crash Handling library for Android projects that automatically stores all crash logs in a file until intentionally cleared. It also records the time of the last exception, making it easy to review and debug issues by sharing the logs.

## 1. Setup
### 1.1 Gradle - Kotlin DSL
Step 1: Project level build.gradle.kts / settings.gradle.kts
dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
repositories {
mavenCentral()
maven("https://jitpack.io")
}
}
Step 2: Module level build.gradle
```
dependencies {
implementation("com.github.Bhuvaneshw:CrashHandler:$version")
}
```
Replace $version with latest version
Latest Version:
[](https://jitpack.io/#Bhuvaneshw/CrashHandler)
Example:
```
dependencies {
implementation("com.github.Bhuvaneshw:CrashHandler:1.0.0")
}
```
### 1.2 Gradle - Groovy DSL
Step 1: Project level build.gradle / settings.gradle
dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
repositories {
mavenCentral()
maven { url 'https://jitpack.io' }
}
}
Step 2: Module level build.gradle
```
dependencies {
implementation 'com.github.Bhuvaneshw:CrashHandler:$version'
}
```
## 2. Usage
### 2.1 Default Crash handler
Extend Application with CrashHandlerApplication and call installCrashHandler()
Koltin
```
class MyApp : CrashHandlerApplication() {
init {
installCrashHandler()
}
}
```
Java
```
public class MyApp extends CrashHandlerApplication {
@Override
public void onCreate() {
super.onCreate();
initCrashHandler();
}
}
```
Register in AndroidManifiest
```
...
```
> [!NOTE]
> This default handler will not restart app after crash. See [Restart after crash](#22-restart-after-crash) section
### 2.2 Formatter and Logger
You can provide Custom Formatter by extending [ErrorMessageFormatter](crashhandler/src/main/java/com/acutecoder/crashhandler/formatter/ErrorMessageFormatter.java) and pass it in [installCrashHandler](#21-default-crash-handler)
You can provide Custom Logger by extending [CrashLogger](crashhandler/src/main/java/com/acutecoder/crashhandler/logger/CrashLogger.java) and pass it in [installCrashHandler](#21-default-crash-handler)
Koltin
```
class MyApp : CrashHandlerApplication() {
init {
installCrashHandler(
errorMessageFormatter = DefaultErrorMessageFormatter, // OR timedErrorMessageFormatter()
logger = AndroidErrorLogger(),
)
}
}
```
Java
```
public class MyApp extends CrashHandlerApplication {
@Override
public void onCreate() {
super.onCreate();
initCrashHandler(DefaultErrorMessageFormatter.INSTANCE, new RestartAppCallback(this), new AndroidErrorLogger());
}
}
```
> [!NOTE]
> The default formatter is [DefaultErrorMessageFormatter](crashhandler/src/main/java/com/acutecoder/crashhandler/formatter/DefaultErrorMessageFormatter.kt) and the default logger is [AndroidErrorLogger](crashhandler/src/main/java/com/acutecoder/crashhandler/logger/AndroidErrorLogger.kt)
> [!NOTE]
> TimedErrorMessageFormatter follows Decorator Patter, to create instance use timedErrorMessageFormatter() extension function for Kotlin and new TimedErrorMessageFormatter(this, DefaultErrorMessageFormatter.INSTANCE) for Java
### 2.3 Restart after crash
Provide RestartAppCallback() while initializing the crash handler
Kotlin
```
class MyApp : CrashHandlerApplication() {
init {
installCrashHandler(callback = RestartAppCallback(this))
}
}
```
Java
```
public class MyApp extends CrashHandlerApplication {
@Override
public void onCreate() {
super.onCreate();
initCrashHandler(
DefaultErrorMessageFormatter.INSTANCE,
new RestartAppCallback(this),
new AndroidErrorLogger()
);
}
}
```
### 2.4 Custom Crash Handler
Override startCrashHandlerActivity() and provide your custom activity class
Kotlin
```
class CustomCrashHandlerApp : CrashHandlerApplication() {
init {
installCrashHandler()
}
override fun startCrashHandlerActivity(defaultActivityClass: Class<*>) {
super.startCrashHandlerActivity(CustomCrashHandlerActivity::class.java) // Provide your custom activity class
}
}
```
Java
```
public class DefaultCrashHandlerApp extends CrashHandlerApplication {
@Override
public void onCreate() {
super.onCreate();
initCrashHandler();
}
@Override
protected void startCrashHandlerActivity(@NonNull Class> defaultActivityClass) {
super.startCrashHandlerActivity(CustomCrashHandlerActivity.class); // Provide your custom activity class
}
}
```
### 2.5 Loading crash data in Activity
> [!CAUTION]
> Calling loadErrorLog() on main thread is not allowed, throws ReadLogOnMainThreadException.
Kotlin
```
val log: ErrorLog = crashHandler.loadErrorLog()
val errors: MutableList? = log.errors
val simplifiedLog: String = log.simplifiedLog()
val lastErrorTime: String? = log.lastErrorTime
```
> [!TIP]
> Using coroutine with IO dispatcher is recommended
Java
```
ErrorLog log = CrashHandlerUtilsKt.getCrashHandler(context).loadErrorLog();
//Works only when the context.applicationContext is an instance of CrashHandler,
//i.e The application must implement CrashHandler, like extending CrashHandlerApplication
List errors = log.getErrors();
String simplifiedLog = log.simplifiedLog();
String lastErrorTime = log.getLastErrorTime();
```
### 2.6 Thread specific crash handler
You can provide specific threads instead of setting it for all threads.
Kotlin
```
class MyApp : CrashHandlerApplication() {
init {
installCrashHandler(threads = arrayOf(myThread1, myThread2, myThreadN))
//OR
// installCrashHandler(
// errorMessageFormatter = DefaultErrorMessageFormatter,
// callback = null,
// logger = AndroidErrorLogger(),
// myThread1, myThread2, myThreadN
//)
}
}
```
Java
```
public class MyApp extends CrashHandlerApplication {
@Override
public void onCreate() {
super.onCreate();
initCrashHandler(DefaultErrorMessageFormatter.INSTANCE, new RestartAppCallback(this), new AndroidErrorLogger(), myThread1, myThread2, myThreadN);
}
}
```
## 3. Custom Crash Handler UI
### 3.1 Custom Activity Implementation
> [!NOTE]
> For more details see the [CrashHandlerActivity](crashhandler/src/main/java/com/acutecoder/crashhandler/CrashHandlerActivity.kt) implementation.
### 3.2 Custom Activity Implementation for Compose
> [!NOTE]
> If you are using compose in your project see [CustomCrashHandlerActivity](app/src/main/java/com/acutecoder/crashhandler/CustomCrashHandlerActivity.kt) for implementation.
