this is my code

OutputStream out = null;
try {
out = new FileOutputStream(getCoverageFilePath(getTargetContext().getPackageName()), false);
Object agent = Class.forName("org.jacoco.agent.rt.RT").getMethod("getAgent").invoke(null);

out.write((byte[]) agent.getClass().getMethod("getExecutionData", boolean.class).invoke(agent, false));

} catch (Exception e) {
Log.d(TAG, e.toString(), e);
} finally {
if (out != null) {
try {
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
