在 Android 设备运行时,虽然其内置了一系列安全功能和机制,但仍然可能受到不同类型的病毒、恶意软件、木马等的攻击。因此,开发人员需要了解如何清除病毒和恶意软件,以保证 Android 设备的安全。
以下是一个 Android 病毒清除示例。
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
public class AntiVirus {
private static final String TAG = "AntiVirus";
public static String getVirusInfo(String packageName) {
String result = null;
try {
byte[] bytes = IoUtils.getBytesFromFile(new File("/data/system/packages.list"));
BufferedReader reader = new BufferedReader(new InputStreamReader(new ByteArrayInputStream(bytes)));
String line;
while ((line = reader.readLine()) != null) {
String[] p = line.split(" ");
if (p[1].equals(packageName)) {
result = getVirusInfoText(p[0]);
break;
}
}
IoUtils.closeQuietly(reader);
} catch (IOException e) {
Log.e(TAG, e.getMessage(), e);
}
return result;
}
private static String getVirusInfoText(String s) throws IOException {
String content = IOUtils.toString(new FileInputStream("/data/system/appops.xml"), "UTF-8");
int i = content.indexOf(s);
if (i >= 0) {
int start = content.lastIndexOf("<pkg ", i);
int end = content.indexOf("</pkg>", i);
int nameStart = content.indexOf("package=\"", start);
int nameEnd = content.indexOf("\"", nameStart + 9);
String packageName = content.substring(nameStart + 9, nameEnd);
return "Virus Found - " + packageName;
} else {
return null;
}
}
}
String packageName = "com.example.myapplication";
String virusInfo = AntiVirus.getVirusInfo(packageName);
if (virusInfo != null) {
Log.d(TAG, "Virus Found: " + virusInfo);
// 清除病毒
PackageManager pm = getPackageManager();
pm.setApplicationEnabledSetting(packageName, PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
pm.getApplicationInfo(packageName, 0);
pm.setApplicationEnabledSetting(packageName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);
Log.d(TAG, "Success Cleaning Virus");
}
