Installing the Pro AAR

After purchase you receive tesseract-android-pro-<version>.aar (and the sample guide). Add it as a local module or file dependency:

// app/libs/tesseract-android-pro-5.5.0.aar
dependencies {
    implementation(files("libs/tesseract-android-pro-5.5.0.aar"))
    implementation("org.jetbrains.kotlinx:kotlinx-coroutines-android:1.9.0")
}

Batch OCR

val batch = TesseractBatch(ocr)
val results = batch.recognizeAll(listOf(bitmap1, bitmap2, bitmap3))
results.forEach { println(it.text) }

Advanced options

val advanced = TesseractAdvanced(ocr)
val hocr = advanced.recognizeHocr(bitmap)     // hOCR / structured output
val tsv  = advanced.recognizeTsv(bitmap)      // TSV with layout

x86_64 emulator support

Pro ships arm64-v8a and x86_64, so it runs on standard Android emulators — handy for CI and desktop testing.
