##### via OpenUPM
The latest version can be installed via using following URL: \
https://openupm.com/packages/com.am1goo.bloodseeker
#### How to use
```csharp
using BloodseekerSDK;
using BloodseekerSDK.Android;
[SerializeField]
private TextAsset _localUpdateFile;
IEnumerator Start()
{
var op = Bloodseeker
//create instance of Bloodseeker
.Create()
//use local encrypted and pre-configured file with actual trails
.SetLocalUpdateConfig(new LocalUpdateConfig
{
file = new TextAssetFile(_localUpdateFile),
secretKey = "YourSecretKey",
})
//or download and update trails from your remote server
.SetRemoteUpdateConfig(new RemoteUpdateConfig
{
//url where sdk have access to file with update
url = "https://your.custom.domain/path/to/file.bmx",
//secret key to decrypt (or "unlock") file
secretKey = "YourSecretKey",
//cache time to live (in seconds)
cacheTTL = 60,
})
//it will be converted to libSomeLibrary.so
.AddTrail(new LibraryTrail("SomeLibrary"))
//any java class can be found here
.AddTrail(new ClassNameTrail("xyz.abc.CheatActivator"))
//you can use package name instead of class name (but it's much slower)
.AddTrail(new PackageNameTrail("xyz.abc"))
//any files in base apk can be found here
.AddTrail(new PathInApkTrail("META-INF/MANIFEST.MF"))
//check node "application/activity" contains "android:name" with value "com.unity3d.player.UnityPlayerActivity"
.AddTrail(new AndroidManifestXmlTrail(AndroidManifestXmlTrail.Looker.UnityPlayerActivity()))
//check node "application/provider" contains "android:name" with value "com.facebook.internal.FacebookInitProvider"
.AddTrail(new AndroidManifestXmlTrail(new AndroidManifestXmlTrail.Looker(
nodes: new string[] { "application", "provider" },
attribute: "android:name",
value: "com.facebook.internal.FacebookInitProvider"
)))
//start seeking anything in these trails
.SeekAsync();
yield return op;
var report = op.report;
switch (report.result)
{
case Report.Result.NotInitialized:
Debug.LogError("SDK not initialized");
break;
case Report.Result.Found:
Debug.LogError($"Found strange code: {string.Join(";", report.evidence)}");
break;
case Report.Result.Ok:
Debug.Log("Everything okay, go ahead!");
break;
}
}
```
## What's next?
- [ ] Redesign of `AndroidManifestXmlTrail` (more flexibility and functionality), serialization support
## Requirements
- Minimal SDK 19 (Android 4.4, KitKat)
## Plugin supports
- Perfectly works with [Beebyte Obfuscator](https://www.beebyte.co.uk/), but in some cases you should add `Bloodseeker.Runtime.dll` to array `Assemblies` in `ObfuscatorOptions.asset`
## Tested in
- Unity 2019.4.x
- Unity 2020.3.x
