Please use this
请使用这个
manifest file
清单文件
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
In Java File
在 Java 文件中
public static String getUniqueIMEIId(Context context) {
try {
TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
if (ActivityCompat.checkSelfPermission(context, Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
// ActivityCompat#requestPermissions
// here to request the missing permissions, and then overriding
// public void onRequestPermissionsResult(int requestCode, String[] permissions,
// int[] grantResults)
// to handle the case where the user grants the permission. See the documentation
// for ActivityCompat#requestPermissions for more details.
return "";
}
String imei = telephonyManager.getDeviceId();
Log.e("imei", "=" + imei);
if (imei != null && !imei.isEmpty()) {
return imei;
} else {
return android.os.Build.SERIAL;
}
} catch (Exception e) {
e.printStackTrace();
}
return "not_found";
}

Try this
试试这个
TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
return;
}
String imei = telephonyManager.getDeviceId();
Add Permission in Manifest.xml
在 Manifest.xml 中添加权限
<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
回答by sanemars
public String getIMEI(final Context context) {
final TelephonyManager ts =
(TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
return ts.getDeviceId()) ;
}
make sure you have Manifest.permission.READ_PHONE_STATE Permission
确保你有 Manifest.permission.READ_PHONE_STATE 权限
