I have

DriverManager.registerDriver((Driver) Class.forName(
                "org.sqlite.JDBC").newInstance());
connection = DriverManager.getConnection("jdbc:sqlite:" + dbname);

First, I changed temp directory, (old begin with "/data/user/0") for Samsung

System.setProperty("java.io.tmpdir","/data/data/com.sample.sqlite/cache"); 

next I changed dbname - in Android alone dbname cause search it in root directory I changed it to /data/data/com.sample.sqlite/cache/a1.db Finally I have:

java.lang.UnsatisfiedLinkError: dlopen failed: library "libsqlitejdbc.so" not found

Maybe libsqlitejdbc.so is, but in other folder than it is searched? I want compare time for JDBC, maybe using .so will faster than pure Java code. Usually Java code is translated to dex which is translated to binary code of snapdragon. What about native code Sqlite JDBC? I think libsqlitejdbc.so is designed for PC with x86 processors? Thus can't works in smartphones?
