即时通讯试图解压缩从sqlite gmail数据库检索数据做一些触发器。我怎样才能做到这一点？从sqlite安卓数据库放气zlib

使用Java代码尝试这种

private String getTextMail(){ 
String mail=""; 
Process sh = null; 
try { 
    sh = Runtime.getRuntime().exec("su", null,null); 
} catch (IOException e) { 
    e.printStackTrace(); 
} 

OutputStream os = sh.getOutputStream(); 
try { 
    os.write(("sqlite3 /data/data/com.google.android.gm/databases/[email protected] \"SELECT bodyCompressed FROM MESSAGES WHERE dateSentMs=(SELECT max(dateSentMs) from messages)\"").getBytes("ASCII")); 
    os.flush(); 
    os.close(); 
    InputStream is=sh.getInputStream(); 
    ByteArrayOutputStream buffer = new ByteArrayOutputStream(); 

    int nRead; 
    byte[] data = new byte[16384]; 

    while ((nRead = is.read(data, 0, data.length)) != -1) { 
     buffer.write(data, 0, nRead); 
    } 
    Inflater decompresser = new Inflater(true); 
    decompresser.setInput(buffer.toByteArray()); 
    byte[] result = new byte[4096]; 
    int resultLength = decompresser.inflate(result); 
    decompresser.end(); 
    sh.waitFor(); 
    mail=new String(result); 
} catch (InterruptedException e) { 
    e.printStackTrace(); 
} catch (IOException e) { 
    e.printStackTrace(); 
} catch (DataFormatException e) { 
    e.printStackTrace(); 
} 

return mail; 
}

Java代码返回我这个编辑：

如果我使用采用gzip -dc PARAMS系统返回：

您确定这是zlib数据吗？显示该值的[hex]（http://www.sqlite.org/lang_corefunc.html#hex）转储。 –

为什么它必须在终端？你不能使用Java代码吗？ –

因为我不能用java获取它。我已经添加了错误。 –

在sqlite3命令行外壳，可以使用writefile() function将blob放入文件中：

SELECT writefile('body.zlib', SomeColumn) FROM SomeTable WHERE ID = 42;

然后use gzip or openssl or zlib-flate or a Python script解压缩这个文件：

printf "\x1f\x8b\x08\x00\x00\x00\x00\x00" | cat - body.zlib | gzip -dc

openssl zlib -d < body.zlib

zlib-flate -uncompress < body.zlib

import zlib 
import sys 

with open('body.zlib', 'rb') as compressed: 
    with open('body.txt', 'wb') as expanded: 
     data = zlib.decompress(compressed.read()) 
     expanded.write(data)

当我使用“printf”\ x1f \ x8b \ x08 \ x00 \ x00 \ x00 \ x00 \ x00“| cat - body.zlib | gzip -dc”返回给我“broken pipe”ON ANDROID。 –

我使用的是printf格式，但gzip给我一个错误（你可以在帖子中看到它） –

如果您能够访问该文件，你可以直接从Java读取值：

SQLiteDatabase db = SQLiteDatabase.openDatabase(
    "/data/data/com.google.android.gm/databases/[email protected]", 
    null, SQLiteDatabase.OPEN_READONLY); 
try { 
    Cursor c = db.rawQuery("SELECT bodyCompressed FROM ...", null); 
    try { 
     if (c.moveToFirst()) { 
      byte[] blob = c.getBlob(0); 

      // ... decompress the blob ... 
     } 
    } finally { 
     c.close(); 
    } 
} finally { 
    db.close(); 
}
